2 x 72 belts  

I am asked all the time were do you buy belts from .     huge selection

USA Knife makers also has a good selection 

super grit .com has low prices

they have 100% felt belts .these work great with green or white buffing bars to polish up your blade to a mirror finish  

1.start off with 2 x 72 belts

stock removal is done with 36 grit to 80 grit belts 

I prefer 60 grit

3M cubitron 2 984 ceramic belt is the best belt available . i HAVE USED ALL KINDS & these cut fast

R980 Blaze ceramic 40 to 60 grit belt also very good

2. next move to 80 - 120 grit to remove previous grind lines off the blade

2x72- R980Y Blaze ceramic or cubitron 2 80 Grit to 120 Grit

3. after refining the blade finish you can use use 180 - 220 - ceramic , silicon carbide or zirconia all will will work for this step

4. 220 on up I use a few different types of belts .

220 up to 800 try silicon carbide belts very nice finish . consistent and predictable

     220 TO 800 GRIT TRY CORK BELTS very fine finish and they last forever S.R . Johnson uses these type of belts on his knives . for break in tips look at to see how he breaks in the cork belts .

3M trizact #'s 100 ,60 , 45, 30,20 ,15 & 5 these are micron belts and grit size is measured in the screen hole size that is used to sift the grains in the separation process . so the larger the number the larger the grit size


NORTON NORAX #'s 100 ,60 , 45, 30,20 ,15 & 5 these are micron belts ALSO

this should get you close to a mirror finish .

buff with a cotton wheeled buffer .with green chrome .

I use all of these belts when working on a knife . over time you will find a combination that works for you .

belts are different in many ways grit , backing weight , cork, ceramic ,aluminum oxide , zirconium. silicon carbide . structured abrassives .

and dont forget about felt buffing belts and leather belts . 

There are three basic set ups for pheer belt grinder

SLACK-of-belt, FLAT PLATEN andcontact wheel. Slack-of-belt is used with low pressure finishing of blades and handles . FLAT Platen have a flat plate backing up the abrasive belt,USED for grinding and finishing flat surfaces SUCH AS FLAT GRINDS


   But contact wheel set ups are by far the most common and the most versatile

In fact, after selection of the proper abrasive belt, the contact wheel is the most important factor in how a belt will ultimately perform. Contact wheels serve as the back-up to the belt and I have found that they can be used for almost 80% of the work on a knife from cleaning pits to profiling the shape and hollow grinding

There are just a few basic concepts to consider when selecting a contact wheel:

1.) Construction: Contact wheels for polishing are made using either rubber-covered aluminum or polyurethane

2.) Hardness: The basic rule of thumb – the softer the wheel, the softer the scratch and the better the conformability to the workpiece. Rubber contact wheels are easily measured in “durometer” hardness values (20 being the softer end of the scale and 90 at the harder end). 50 duro to 70 is ideal for knife making 90 duro is the hardest wheel that should be used .

3.) Serration: On rubber contact wheels, serrations are grooves cut into the face of the wheel. This action allows more pressure on the belt which is supported on the “lands” between the grooves (as compared to a smooth-faced wheel). The pattern of “grooves and lands” allows better breakdown of the abrasive grain and also cooler cutting with less working pressure

smooth faced wheels are much better for finishing blades

. Contact wheels can be ordered with various groove-to-land ratios, groove depths and shapes and angles of serration.

A typical contact wheel for general purpose grinding or finishing would be 8" to 14” diameter, 2" wide 50-70 durometer hardness, 3/8” to 3/8” groove-to-land ratio, 3/8” groove depth and have a 45° serration angle.

belts in 25 packs or 50 3m AO 577 & ceramics 

seamount knife works lots of very good info , very detailed info on steel and other topics

master list of all kinds of knife stuff




1. always wear form fitting Gloves avoid loose fitting gloves ,

wear eye protection and a leather apron

2. never hold the blade in a manner that can catch the belt edge and throw it back at you ,avoid using the section above the contact wheel to sharpen a blade . I discovered it the hard way ,I barely had enough time to jump to the side to avoid a flying razor sharp knife that was launched right at me . it's just not worth the risk .

3 let the belt do the work , avoid jamming your work into the belt . if your hands slip then chances are you will end up pushing your fingers right into the belt , if your not wearing gloves then you may grind off your finger tips .

grinding steel can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the belt grinder . Using the machine with respect and caution will considerably lessen the possibility of personal injury.

However, if normal safety precautions are overlooked or ignored,personal injury to the operator may result.

Safety equipment such as , push sticks, leather gloves , leather apron ,goggles, dust masks and hearing protection can reduce your potential for injury. But even the best safety equiptment won’t makeup for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop.If a procedure feels dangerous, don’t try it.

Figure out an alternative procedure that feels safer. REMEMBER: Your personal safety is your responsibility.This machine was designed for certain applications only.

.3. ALWAYS WEAR EYE PROTECTION. Wear safety glasses. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses. Also use face or dust mask if cutting operation is dusty. These safety glasses must conform to ANSI Z87

.5. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents

.6. DON’T USE IN DANGEROUS ENVIRONMENT. Don’ tuse power tools in damp or wet locations, or expose them to rain. Keep work area well-lighted.

7. KEEP CHILDREN AND VISITORS AWAY. All children and visitors should be kept a safe distance from work area.

8. MAKE WORKSHOP CHILDPROOF – with padlocks,master switches, or by removing starter keys.

9. DON’T FORCE TOOL. It will do the job better and be safer at the rate for which it was designed

.10. Don’t force tool or attachment to do a job for which it was not designed

.11. WEAR PROPER APPAREL. No loose clothing, ,neckties, rings, bracelets, or other jewelry to get caught in the belt or wheels . Nonslip footwear is recommended. Wear protective hair covering to contain long hair.

12. SECURE WORK. hold the piece firmly

.13. DON’T OVERREACH. Keep proper footing and balance at all times.

14. MAINTAIN TOOLS IN TOP CONDITION. check bearings and bolts Keep clean for best and safest performance.

.15. DISCONNECT MOTOR AND DRIVE before servicing
