Top questions from beginner knife makers.
What is the best grit progression for metal?
- For all coarse-medium grits (36-120), we recommend using our Firestorm II ceramic belts. They represent our newest grain technology. They cut cool, self-sharpen and last approximately 30% longer than previous ceramics.
- They are available in grits: 36, 40, 50, 60, 80, 100, 120. (It is ok to skip 1-2 grits)
- We recommend: 36 then 60 then 120.
- They are available in grits: 36, 40, 50, 60, 80, 100, 120. (It is ok to skip 1-2 grits)
- For the medium-fine grits (180-220), we recommend using our Blue Ceramic belts. They cut cool and self-sharpen.
- They are stocked in grits (180 & 220).
- We recommend jumping from 120 Firestorm II to 220 grit Blue Ceramic.
- They are stocked in grits (180 & 220).
- For the fine-super fine grits (320-800), ceramic is not available finer than 220 grit. A/O is the primary grain used on fine grits. We recommend our Green J-Flex A/O belts.
- They are available in grits: 60, 80, 120, 180, 220, 320, 400, 600 & 800
- We recommend jumping from 220 Blue Ceramic to: 400 then 600 AO.
- They are available in grits: 60, 80, 120, 180, 220, 320, 400, 600 & 800
If you would like to go finer, we offer 1200 and 2000 grit blue film belts.
To hone your edge, we offer a “Felt” belt.
The belts mentioned above are all included in the starter kits below. They can also be purchased separately.
Can belts be used wet
- If the belt backing is Polyester, water will not cause any problem. They can be used with any amount of water or cutting fluid. (All Firestorm belts are Polyester backed)
- If the backing is not Polyester (either cotton or poly/cotton blend), it is ok to “dip” the blade in water to cool it, but they should not be used with a mister or drip method which will get the belts too wet which can cause a problem. (Blue Ceramic and Green AO J-Flex are not Polyester)
Do eraser sticks really work?
- They work great when the belts get clogged with common handle materials (G10, wood, antler, bone, etc.), regardless of the grit.
- On metal, they can be effective when used on the finer grits. They are generally not very effective on coarse grits when the metal has adheared to the grains.
