3M™ Cubitron™ II 984F knife sharpening belts feature precision-shaped ceramic grain that cuts faster, runs cooler, and lasts significantly longer than conventional ceramic belts. They are ideal for heavy stock removal, edge repair, bevel resetting, and demanding sharpening applications where speed, consistency, and long belt life matter.
Trusted by professional sharpeners and knife makers, 3M™ Cubitron™ II 984F belts deliver aggressive cutting performance while maintaining exceptional durability. Personally tested in our sharpening shop, they remain one of our top choices for repairing damaged edges, resetting bevels, and preparing blades for finer grit polishing and stropping.
⭐ Cliff's Notes
Cuts fast, runs cool, and lasts longer than conventional ceramic belts.
Use light to medium pressure — let the abrasive do the work.
My first choice for repairing damaged edges and resetting bevels.
A staple belt in our sharpening shop and one I recommend to every serious sharpener.

A good belt saves time, but even the best belts wear out!
Do yourself a favor and always keep a few new ones in stock. I've wasted SOOOO much time trying to get one more knife out of a belt. No belt is worth an extra half hour of your time, lol.
These belts work fast and stay cool.
Seeing fast progress on my projects is very rewarding!!
I ordered a selection of various belts to try on my new Vevor 1x30 and am impressed with all of them. Cubitron, trizact, scotch Brite, leather- all work well. I was a little hesitant to order from somewhere as far away as Hawaii, but the shipping was reasonable and the belts well packaged. Will be ordering more.
Thanks Cliff! Made the move to Cubitron and Trizacs. There are other ceramic and structured belts. But, buy now cry now. Lol Because the amount of work you are able to produce per belt they more than pay for themselves. Shipping from Cliff Curry is fantastic! And he is always ready to help with a product question or technique advice.

Love these Cubitron belts for initial work on blades. I use this 120 to fix any damage and set the bevel for finishing work. They cut fast, run cool and last a long time. Worth every penny.
The Curon 3M belts cut very nice a little less friction, and they wear a little better.
Just finished this project including the Sonoran desert ironwood Burrel.
I have been sharpening at volume for 17 years. I have used almost every belt, wheel, machine, or compound on the market.
The cubitron is the best belt I have found for a clean precision cut. This belt is one of the main building blocks that have made me successful in my profession.
Curry custom cutlery is my trusted source for knife sharpening lessons, as well as products and I have yet to be disappointed! The nylon abrasive Wheels can only be found here and they are absolutely incredible for satin polishing knives or removing rust and patina, and few sharpening belts in the world compare to the cubitron. Thanks for all you do and for the free content you continue to share
Beast of a belt. I use it to reprofile knives and to sharpen knives that I've never sharpened before. Gets the job done extremely fast and keeps metal cool
