Finishing belts are consumables — price them that way
Fine grits wear on schedule: every blade runs the same sequence, so a busy shop knows exactly how many 220s and 400s a month eats. The 20-pack keeps your per-belt cost down (X-weight 120 grit: $3.45/belt vs $4.00 in the 3-pack) and your sequence unbroken.
Same aluminum-oxide construction as the 3-packs: past ~120 grit, premium grains stop earning their price — A/O finishes just as well for less.

Suitability
Who should buy the 20-pack?
Buy bulk if
You finish blades or parts on a schedule and burn through fine grits
You already know your sequence and materials
You want the lowest per-belt cost on your most-used grits
Start with a 3-pack if
You’re still dialing in your finishing sequence
You need a grit the bulk pack doesn’t list
Technical details
Same belt, full details
All specs match the Finishing & Sharpening 3-pack.
Construction
Aluminum-oxide grain on X-weight cloth (platen work) or J-Flex flexible backing (slack-belt contours).
Grit sequencing
Step one or two grits at a time — skipping grits destroys the finer belt and the finish.
Machine fit
Standard 2″ x 72″ belts for all common knife grinders.
I accidentally bought these belts by mistake instead of the shredder belt I usually get. They definitely don't hold up and cut like the shredder belts. I will be more careful next time.
Combat Abrasives has been supplying great belts at a reasonable price, especially the bulk packs. Belts stay cooler than others I’ve had and clean easily when needed.
I have never had any tracking problems with their belts as I have with another brand.
Shipping time is slower than other companies, but has never been an issue as long as you order before you run out.
Thank you Combat Abrasives
