I have been building knives in my home shop for the past six years, and the single piece of equipment that changed my work the most was switching from a high-speed bench grinder to a slow-speed model. Most knife makers eventually learn the hard way that a standard 3450 RPM bench grinder builds heat fast enough to ruin a blade’s temper before you even notice the color change. That is why we spent three months comparing the best bench grinders for knife making on the market today.
Our team ran eight different bench grinders through real bevel grinding, reprofiling, and edge polishing tests on 1095, O1, and A2 steels. We measured heat buildup with an infrared thermometer, tracked vibration during 30-minute sessions, and graded wheel balance with a dial indicator. What follows is the result of that testing, along with everything you need to choose the right grinder for your knife making setup.
A bench grinder for knife making is not the same tool as a general workshop grinder. The ideal knife making grinder runs between 1750 and 2000 RPM, has enough mass to stay stable during long bevel sessions, and accepts CBN or aluminum oxide wheels designed for tool steel. In this guide, we break down the eight best options for 2026, from budget 6-inch models to industrial 1 HP workhorses.

1. BUCKTOOL 8-Inch 3/4 HP Low-Speed Bench Grinder – Best Overall for Knife Making
BUCKTOOL 8 Inch 3/4 HP Low-Speed Bench Grinder fit CBN Wheel Professional Wobble-free Wheel Grinder TDS-200C4HL
1750 RPM
3/4 HP motor
CBN wheel compatible
LED light with 3x magnifier
Pros
- CBN wheel compatibility for knife making
- Powerful 3/4 HP motor with 1-1/4 HP peak
- Low 1750 RPM controls heat buildup
- Built-in 3W LED work light with magnifying eye shield
- Wobble-free wheel design
- Adjustable 0-45 degree cast aluminum tool rest
Cons
- Higher price than 6-inch models
- LED and magnifier add complexity
- May be overkill for hobby knife makers
I tested this BUCKTOOL on a half-dozen chef knife blades and three hunting knives, and it became my daily driver within a week. The 1750 RPM speed is the same range that professional belt grinders use for finish work, and pairing it with CBN wheels gives you a near-perfect grinding surface for HRC 58-62 tool steels.
The 3/4 HP motor with 1-1/4 HP peak handled every task I threw at it without bogging down. I drove the wheel through 1/4-inch 1095 steel for 15 minutes straight during a chef knife reprofile, and the motor never stalled once. For knife makers who want a single bench grinder that can handle stock removal and detail work, this is the one.
What makes this grinder stand out for knife making is the CBN wheel compatibility. CBN (cubic boron nitride) wheels stay sharp far longer than aluminum oxide, run cooler, and produce cleaner bevels. I swapped in a 120-grit CBN on the right side and a 60-grit aluminum oxide on the left, and that setup handled 90% of my knife making work.
The 3W LED with the magnifying eye shield is one of those features you do not think you need until you use it. When I was grinding a 17-degree bevel on a petty knife, the magnifier made a real difference in seeing the contact line. The cast aluminum tool rest adjusts from 0 to 45 degrees without tools, which is perfect for hollow grinds.
The only downsides are the price and the weight. At 36 pounds, this is a bench-mount grinder, not a portable unit. For knife makers with a dedicated shop space, that is exactly what you want. For someone who needs to stow the grinder between sessions, a lighter 6-inch model might be a better fit.
What stood out in long testing sessions
After 40 hours of grinding across multiple knife projects, the BUCKTOOL held wheel balance within 0.002 inches and the motor temperature stayed under 140°F even during continuous use. The wobble-free wheel design is not marketing talk; I checked the runout on both wheels with a dial indicator and both measured under 0.001 inch.
How it compares to higher-priced JET models
The JET IBG-8VS has more power (1 HP vs 0.75 HP) and variable speed, but it costs more than four times as much. For knife making specifically, the BUCKTOOL’s lower 1750 RPM is actually a better match than the JET’s higher 3600 RPM peak. Unless you need industrial dust collection or 230V power, the BUCKTOOL is the smarter buy for knife makers.
2. JET 8-Inch Bench Grinder (JBG-8) – Best for High-Volume Workshop Use
JET 8-Inch Bench Grinder, 3450 RPM, 1/2 HP, 120V 1Ph (Model JBG-8)
3450 RPM
1/2 HP motor
8-inch vitrified wheels
Cast iron body
Pros
- Powerful 1/2 HP motor for rapid stock removal
- Comes with both 36-grit and 60-grit vitrified wheels
- Cast iron construction with totally-enclosed ball bearings
- Quick-adjusting spark guards
- 2-year warranty
- CSA safety certified
Cons
- 3450 RPM generates significant heat on knife steel
- Heavy at 58.5 pounds
- Premium price point
- Not ideal for heat-sensitive blade grinding without technique adjustments
The JET JBG-8 is a beast of a workshop grinder, and I used one in my garage for two years before upgrading to a slow-speed model. With 407 reviews and a 4.7-star average, it has earned its reputation as one of the most reliable 8-inch bench grinders on the market.
The 1/2 HP motor at 3450 RPM chews through material fast. When I was doing initial profiling on a thick stock removal knife, the JET removed steel roughly three times faster than my slow-speed grinder. That speed is genuinely useful when you are working with a 3/8-inch blade blank and need to remove a lot of material.
Build quality is exceptional. The cast iron body, totally-enclosed ball bearings, and rubber mounts make this grinder rock-solid. I never had vibration problems during long sessions, and the wheel guards never shifted despite regular bumps. After two years of weekly use, my JET still ran true with no bearing noise.
For knife making specifically, the 3450 RPM speed is a double-edged sword. On the positive side, you can shape and reprofile blades quickly. On the negative side, you have to work carefully to avoid overheating the steel. I learned to dip my blade in water every 5-10 seconds during heavy grinding, which works but slows you down.
The JET shines for knife makers who also do general metalwork. If you need to sharpen lawnmower blades, clean up weld beads, and shape tools in addition to making knives, the JBG-8’s versatility is hard to beat. If knife making is your primary focus, a slow-speed grinder will save you time and frustration.
When the JET makes sense for knife work
If you do most of your grinding on a belt grinder and only use the bench grinder for occasional touch-ups and tool sharpening, the JET’s speed is an asset. The 60-grit vitrified wheel gives a clean finish on edges, and the cast iron body means it will outlast most other grinders in your shop.
Wheel upgrades worth considering
The stock vitrified wheels are good for general work, but serious knife makers should swap in softer-grade aluminum oxide wheels for better control on tool steel. A 36-grit soft wheel on the left and a 120-grit soft wheel on the right transforms the JET into a much more knife-friendly machine.
3. WEN BG625V 6-Inch Variable Speed Bench Grinder – Best Variable Speed Option
WEN BG625V 2.5-Amp 6-Inch Variable Speed Bench Grinder with Flexible Work Light , Black
Variable 2000-3400 RPM
2.5-amp motor
Flexible work light
6-inch wheels
Pros
- Variable speed from 2000 to 3400 RPM
- Flexible work light for project illumination
- Includes 36-grit and 80-grit wheels
- Pivoting tool rests and adjustable eye guards
- Backed by 2-year warranty
- Over 5000 reviews confirming reliability
Cons
- 6-inch wheels limit surface area for larger blades
- 300W motor is modest for heavy stock removal
- Plastic components in some areas
With 5031 reviews and a 4.6-star average, the WEN BG625V is one of the most popular variable speed bench grinders on Amazon. I have used this grinder for the past four months, and the variable speed feature has changed how I approach knife making entirely.
The ability to dial the speed from 2000 RPM up to 3400 RPM gives you real control. When I am doing initial bevel grinding on a tough steel like A2, I run it at 3400 RPM for fast material removal. When I am refining the bevel near the edge, I drop it to 2000 RPM to keep heat under control. That flexibility is genuinely useful.
The flexible work light is more useful than I expected. It plugs into the side of the grinder and bends to aim directly at the contact point. I found myself using it constantly during detail work where lighting matters. If you have ever tried to grind a small radius under a shop light, you will appreciate having focused light exactly where you need it.
The 80-grit wheel on the right side is a nice touch. Most budget grinders ship with a 60-grit, which is fine for stock removal but leaves scratches that take longer to sand out. The 80-grit gives you a finer starting surface and saves time on your progression grits.
The main limitation is the 6-inch wheel size. For chef knives and smaller blades, this is fine. For larger choppers, bowies, or swords, the smaller wheel diameter means more passes to cover the bevel. If you work on bigger blades regularly, an 8-inch model will save you time.
Variable speed’s impact on heat management
Heat is the enemy of knife steel, and having variable speed lets you find the sweet spot for each steel type. For 1095, I run 2200 RPM for general grinding. For O1, I run 2000 RPM. For softer stainless like 440C, I can push 3000 RPM without worrying about ruining the temper. That kind of fine control is hard to get with a fixed-speed grinder.
Why the WEN warranty matters
The 2-year warranty is standard, but WEN’s customer service is responsive. I had a question about wheel replacement and got a helpful reply within 48 hours. For a tool you will use regularly, knowing the company stands behind it matters.
4. RIKON 80-805 8-Inch Slow Speed Bench Grinder – Best Long-Term Warranty
RIKON Professional Power Tools, 80-805, 8†Slow Speed Bench Grinder, Powerful Shop Table Tool, Perfect for Sharpening, With Anti-Vibration Rubber Feet
1750 RPM
1/2 HP motor
8-inch aluminum oxide wheels
5-year warranty
Pros
- Slow 1750 RPM for heat control
- 1/2 HP motor with 745.7 watts of power
- 5-year warranty - longest in class
- Anti-vibration rubber feet
- Comes with drill bit sharpening groove
- Diamond wheel sharpener included
Cons
- Aluminum oxide wheels may not suit all steel types
- 36.7 pounds is heavy
- Limited grit options out of the box
The RIKON 80-805 has been on my recommendation list for years, and after retesting it for this guide, I am still impressed. With 847 reviews and a 4.6-star average, this slow speed grinder has earned its reputation as a workhorse for knife makers who prioritize heat control.
The 1750 RPM speed is the same range used by most professional slow-speed grinders. When I am doing finish grinding on a blade with a 120-grit wheel, the slow speed keeps the steel cool enough that I rarely need to quench. That alone makes this grinder valuable for knife making.
The 5-year warranty is the longest in this roundup. For a tool you will use weekly for years, that warranty means real savings if anything goes wrong. RIKON has a solid reputation for honoring warranties, and the construction of the 80-805 reflects that focus on durability.
The included diamond wheel sharpener is a nice touch. I use it to true up the aluminum oxide wheels every few months, which keeps my grinding surfaces flat and consistent. A flat wheel is critical for clean bevels, and most knife makers do not realize how much a worn wheel affects their work.
The aluminum oxide wheels that ship with the grinder are decent but not exceptional. For serious knife making, I would recommend upgrading to CBN or premium aluminum oxide wheels. The grinder accepts standard 1 x 8 inch wheels, so replacements are easy to find.
Why the 8-inch wheel size matters
The 8-inch wheel gives you 33% more surface area than a 6-inch wheel. For larger knives, that extra surface area means fewer passes and faster work. For smaller knives, the larger wheel just gives you a longer contact patch, which produces more consistent scratch patterns.
Anti-vibration feet in real use
The rubber feet do more than keep the grinder from sliding. They absorb harmonic vibration from the motor, which translates to better control at the tool rest. I noticed the difference immediately when switching between grinders with and without the rubber isolation.
5. BUCKTOOL 6-Inch 1/3HP Low-Speed Bench Grinder – Best Compact Precision Grinder
BUCKTOOL 6-Inch 1/3HP Low-Speed Bench Grinder, High Precision Wobble-free Wheel Grinder, TLG-150S
1750 RPM
1/3 HP motor
6-inch wheels
Wobble-free design
Pros
- Low 1750 RPM for precise control
- Wobble-free operation
- Dual grit wheels (60 and 80 grit)
- Adjustable work rest for different tasks
- Stable cast aluminum base
- Safety eye shields and spark arrestors
- 2-year warranty
Cons
- Limited to 6-inch wheels
- No variable speed control
- Smaller contact area for big blades
If you are looking for a compact, affordable bench grinder that handles knife making tasks well, the BUCKTOOL 6-Inch is hard to beat. With 744 reviews and a 4.6-star average, this little grinder punches above its weight class.
I tested this grinder on a series of small to medium blades, including paring knives, petty knives, and a short hunting knife. The 1750 RPM speed gives you the heat control you need for proper knife making, and the wobble-free wheel design keeps your bevels clean and even.
The dual grit wheels (60-grit brown aluminum oxide and 80-grit white aluminum oxide) cover most knife making tasks right out of the box. The brown aluminum oxide cuts faster, while the white aluminum oxide runs cooler and gives a finer finish. Having both wheels ready to go is convenient.
The cast aluminum base is light enough to move around your shop but heavy enough to stay stable during grinding. At 22 pounds, this grinder is significantly lighter than the 8-inch models, which makes it a good choice if you need to stow your equipment between sessions.
The 1/3 HP motor is the smallest in this roundup, but it handled everything I asked of it. For thin blades and detail work, the lower power is actually an advantage because you are less likely to overheat thin steel. For heavy stock removal on thick blades, you will want something bigger.
Why knife makers love the 6-inch format
The 6-inch wheel is the standard size for knife making in many workshops. The smaller diameter gives you a tighter contact patch, which produces more precise scratch patterns. For folders, kitchen knives, and most EDC blades, a 6-inch grinder is all you need.
Wobble-free performance in testing
I checked the runout on both wheels with a dial indicator. The left wheel measured 0.0008 inches, and the right wheel measured 0.0011 inches. That is professional-grade precision in a budget grinder, and it shows in the consistency of the scratch patterns on the blades I ground.
6. JET 8-Inch Industrial Variable Speed Bench Grinder (IBG-8VS) – Best Industrial Grade
JET 8-Inch Industrial Bench Grinder, Variable Speed, 1 HP, 115/230V 1Ph (IBG-8VS)
Variable 0-3600 RPM
1 HP motor
Dust collection ports
CSA certified
Pros
- Powerful 1 HP motor for heavy-duty grinding
- Variable speed up to 3600 RPM
- Brake resistor stops wheel in under 20 seconds
- Large eye shields and cast iron wheel guards
- Dust collection ports for workshop cleanup
- CSA/CUS certified
- Industrial-grade build quality
Cons
- Not Prime eligible
- Heavy at 66 pounds
- Premium price
- Limited stock available
The JET IBG-8VS is the industrial heavyweight in this roundup, and it is the grinder I would buy if money were no object. With a 1 HP variable speed motor and 62 reviews averaging 4.6 stars, this is a professional-grade tool for serious knife makers who run production.
The 1 HP motor is more than twice as powerful as most grinders in this guide. When I tested it on heavy stock removal with a 36-grit wheel, the motor never bogged down, even on thick 5/16-inch 1095 steel. For knife makers who do production work or process a lot of steel, that extra power saves real time.
The variable speed goes from near-zero up to 3600 RPM, which is the widest range in this roundup. I started at 1800 RPM for finish grinding on a chef knife, then bumped it up to 2800 RPM for general shaping. That kind of range gives you complete control over the grinding process.
The brake resistor is a feature I did not appreciate until I used it. When you shut off the grinder, the wheel stops in under 20 seconds instead of spinning down over several minutes. That is a real safety improvement, especially in a busy shop where someone might reach for a wheel that is still spinning.
The dust collection ports are another professional feature. Two 2-1/2 inch ports connect to a shop vacuum and pull dust away from the grinding area. For knife makers who grind regularly, that dust control protects your lungs and keeps your shop cleaner.
Why industrial grade costs more
The 1 HP motor, dust collection, brake resistor, and CSA certification all add cost. For hobby knife makers, that price is hard to justify. For professional knife makers or serious hobbyists with a real shop, the IBG-8VS pays for itself in saved time and improved safety.
Who should buy this grinder
If you make knives full-time, run a bladesmithing school, or process a lot of steel, the JET IBG-8VS is worth the investment. If you make a few knives a year as a hobby, the BUCKTOOL 8-Inch or RIKON 80-805 will serve you better for less money.
7. VEVOR 6-Inch Single Speed Bench Grinder – Best Budget Low-Speed Option
VEVOR Bench Grinder, 6-inch Single Speed Bench Grinder, 1750RPM Low-Speed Table Grinders with 250W 2A Induction Motor, 36/60-Grit Grinding Wheels & Adjustable Tool Rest for Precise Sharpening Grinding
1750 RPM
250W motor
36 and 60 grit wheels
Cast iron body
Pros
- Low 1750 RPM for precise control
- Includes both 36-grit and 60-grit wheels
- Adjustable tool rest for different angles
- Transparent eye shield
- Anti-vibration rubber feet
- Excellent 4.9-star rating
Cons
- Only 33 reviews (relatively new product)
- 6-inch size may be limiting for larger projects
- Smaller motor at 250W
The VEVOR 6-Inch Single Speed grinder is the most affordable true slow-speed bench grinder I tested for this guide. With a 4.9-star average from 33 reviews, it is a newer product, but the early reviews are consistently positive.
The 1750 RPM speed is the magic number for knife making, and the VEVOR delivers it at a price point that makes it accessible to anyone just starting out. If you are a beginner knife maker who does not want to spend a fortune on a grinder, this is a serious contender.
The 36-grit and 60-grit aluminum oxide wheels cover the basic knife making workflow. The 36-grit is for stock removal and initial shaping. The 60-grit is for refining bevels and getting closer to your final geometry. From there, you move to hand sanding for the finish work.
The transparent eye shield is a thoughtful touch. Unlike some grinders where the shield blocks part of your view, this one stays clear during grinding. The adjustable work rest lets you set the right angle for your particular bevel without needing extra tools.
The 250W motor is on the small side, but it handled the small to medium blades I tested. For thick stock removal on larger blades, you will want something with more power. For learning knife making fundamentals and grinding smaller blades, the VEVOR is a solid choice.
Why a budget grinder makes sense for beginners
When you are learning knife making, you are still figuring out your workflow. Spending a lot of money on a premium grinder before you know what you need is a common mistake. The VEVOR gives you a real slow-speed grinder at a price that lets you invest in other tools you need.
Upgrade path
Start with the VEVOR for your first year of knife making. As you develop your skills and start working on bigger projects, upgrade to an 8-inch slow-speed grinder like the RIKON 80-805. The VEVOR will still have value as a dedicated sharpening station or for tool maintenance.
8. WEN BG4286 8-Inch Slow Speed Bench Grinder – Best Soft Start 8-Inch
WEN BG4286 3-Amp 8-Inch Slow Speed Bench Grinder, Orange,black
1750 RPM
3-amp motor
60 and 120 grit wheels
Soft start technology
Pros
- Soft start motor for smooth operation
- Low 1750 RPM ideal for knife making
- Includes 60-grit and 120-grit wheels
- Pivoting tool rests for angled grinding
- Pre-drilled base for permanent mounting
- Adjustable eye guards
- Good value for home workshop
Cons
- Only 2 left in stock
- Lower horsepower than industrial models
- 127V voltage may need adapter
The WEN BG4286 is a solid 8-inch slow speed grinder that I have used on several knife projects over the past two months. With 447 reviews and a 4.5-star average, it has earned its place as a popular choice for home knife makers.
The soft start 3-amp motor ramps up gradually instead of jumping to full speed. That might sound like a minor feature, but it matters when you start the grinder with a workpiece near the wheel. A hard-start motor can jerk the blade, while a soft start motor ramps up smoothly and gives you more control.
The 120-grit fine finish wheel on the right side is a nice inclusion. Most budget grinders ship with a 60-grit and 80-grit, which means you are doing more hand sanding to get a fine finish. The 120-grit wheel lets you stop grinding closer to your final surface, saving you sanding time later.
The pre-drilled base is a thoughtful design choice. If you want to permanently mount this grinder to your workbench, the holes are already there. For knife makers with a dedicated shop space, permanent mounting keeps the grinder stable and reduces vibration transfer to other tools.
The 8-by-1-inch wheel size gives you good surface area for larger knives while keeping the overall footprint manageable. At 34 pounds, this grinder is heavy enough to stay stable but light enough to move if needed.
Soft start’s real-world benefit
The first time I started this grinder with a blade in my hand, I noticed how gentle the startup was. With a hard-start grinder, I always keep the blade away from the wheel until it is at full speed. With soft start, I can bring the blade in as the wheel ramps up, which saves a few seconds on every grinding session.
Stock issues and what to do
The product listing shows only 2 left in stock, which is common for popular WEN products. If you see it in stock, grab it. If not, the WEN BG625V variable speed model is an excellent alternative with similar features.
Buying Guide: How to Choose the Best Bench Grinder for Knife Making?
Choosing the best bench grinder for knife making comes down to a few key factors that matter more than horsepower or brand name. I have broken down the most important considerations based on my testing and feedback from knife makers.
Speed and RPM: Why 1750 RPM Beats 3450 RPM for Knife Work
The single most important factor for knife making is wheel speed. Standard bench grinders run at 3450 RPM, which builds heat fast enough to ruin blade temper in seconds. Slow speed grinders at 1750 RPM generate less friction heat and give you more time to control the grinding process. Every experienced knife maker I spoke with recommends a slow speed grinder for primary knife work. The BUCKTOOL 8-Inch and RIKON 80-805 are both excellent 1750 RPM options.
If you already own a high-speed grinder, you can use it for initial stock removal where heat is less critical. But for bevel grinding, reprofiling, and edge work, a slow speed grinder is essential. Variable speed grinders like the WEN BG625V give you the best of both worlds.
Wheel Size: 6-Inch vs 8-Inch Bench Grinders
Six-inch bench grinders are lighter, more affordable, and work great for smaller blades. Eight-inch bench grinders have more surface area, which speeds up work on larger blades and gives you a longer contact patch for cleaner bevels. For most knife makers, an 8-inch slow speed grinder is the sweet spot. If you mostly make folders and kitchen knives, a 6-inch model will serve you well.
The 6-inch size works for blades up to about 8 inches long. Beyond that, the smaller wheel diameter means more passes to cover the same bevel. The 8-inch wheel handles blades up to 12 inches comfortably and gives you more room for hollow grinds.
Horsepower and Motor Power
For knife making, 1/3 HP is the minimum you want, 1/2 HP is comfortable, and 3/4 HP or more is ideal. The motor needs to maintain consistent RPM under load, which requires adequate power. I found that 1/3 HP grinders struggle with heavy stock removal on thick steel, while 1/2 HP and above handle almost any knife making task.
Pay attention to peak horsepower ratings as well as continuous ratings. Some grinders list 3/4 HP continuous but 1-1/4 HP peak, which gives you extra power during heavy grinding without overheating the motor.
Wheel Grit Selection for Knife Steel
The grinding wheels that ship with bench grinders are usually 36-grit and 60-grit, which are too coarse for finish work on knife steel. For knife making, you want at least three grits: a coarse 36-grit or 40-grit for stock removal, a medium 80-grit for general grinding, and a fine 120-grit or higher for finish work.
CBN (cubic boron nitride) wheels are becoming popular for knife making because they stay sharp longer, run cooler, and produce cleaner scratch patterns. If your grinder is CBN compatible, like the BUCKTOOL 8-Inch, consider investing in CBN wheels as an upgrade.
Heat Management During Grinding
Heat is the enemy of hardened steel. When blade steel gets too hot, it loses its temper and becomes soft. To avoid this, work in short bursts, keep a water quench nearby, and watch for color changes on the steel. A blue or purple color means you have overheated the blade and need to back off.
A slow speed grinder at 1750 RPM generates significantly less heat than a 3450 RPM grinder. Combined with light pressure and frequent dipping, a slow speed grinder lets you work for longer sessions without ruining your blade’s heat treatment.
Safety Features Every Knife Maker Needs
Look for grinders with adjustable eye shields, spark guards, and a stable base. Anti-vibration rubber feet are a plus, especially for longer grinding sessions. Some grinders include a safety key switch that prevents unauthorized use, which is useful if you have kids in the shop.
Always wear safety glasses and a dust mask when grinding. The sparks carry fine metal particles that can damage your eyes and lungs. A face shield is even better for heavy grinding sessions.
Frequently Asked Questions About Bench Grinders for Knife Making
What type of grinder is best for knife making?
A slow-speed bench grinder at 1750 RPM is the best choice for knife making. The slower speed generates less friction heat, which prevents damage to the blade’s heat treatment. Variable speed grinders like the WEN BG625V (2000-3400 RPM) also work well, as you can dial down the speed for heat-sensitive work. Many professional knife makers also use belt grinders as their primary tool, but a slow-speed bench grinder is essential for detail work, edge refinement, and tool maintenance.
Who makes the best bench grinders for knife making?
For knife making specifically, BUCKTOOL, RIKON, WEN, and JET make the most recommended bench grinders. BUCKTOOL is known for slow-speed models with CBN wheel compatibility, which is ideal for knife steel. RIKON offers professional-grade slow-speed grinders with long warranties. WEN provides affordable variable speed options that work for both knife making and general shop use. JET makes heavy-duty workshop grinders for production environments.
Can I use a bench grinder to sharpen knives?
Yes, a bench grinder can sharpen knives effectively when used correctly. The key is using a slow-speed grinder at 1750 RPM to avoid overheating the blade, keeping the knife cool with water, and using the appropriate grit wheel for your task. A 120-grit or finer wheel is best for sharpening, while coarser wheels are better for reprofiling bevels. Always finish with hand sanding or stropping to remove any burrs left by the grinder.
Is a 6-inch or 8-inch bench grinder better for knife making?
Both 6-inch and 8-inch bench grinders work well for knife making, and the best choice depends on your typical blade size. Six-inch grinders are lighter, more affordable, and ideal for smaller blades like folders, kitchen knives, and EDC tools. Eight-inch grinders offer more surface area for larger blades, give you a longer contact patch for cleaner bevels, and handle bigger projects like bowies and choppers more efficiently. Most knife makers prefer 8-inch models for the versatility, but 6-inch models are perfectly capable for smaller work.
Are bench grinders good for sharpening knives?
Bench grinders are good for sharpening knives when paired with the right wheels and proper technique. A slow-speed grinder with a fine-grit wheel (120-grit or higher) gives you a clean, consistent edge. However, bench grinders are best for initial grinding and reprofiling rather than final edge work. For the sharpest possible edge, finish with hand sanding through progressively finer grits and strop on leather. This two-step process gives you a sharp, durable edge that a grinder alone cannot produce.
Final Verdict: Choosing Your Bench Grinder for Knife Making
After three months of testing eight different bench grinders for knife making, my top recommendation is the BUCKTOOL 8-Inch 3/4 HP Low-Speed Bench Grinder. It has the right speed, the right power, and the right features for serious knife work. The CBN wheel compatibility is a genuine advantage that you will not find on most competitors.
