Always buy these belts.
Love the belts!!
I exclusively use your belts. I love them! Thank you.
Love your belts. Been using them exclusively for 2 years now. The results speak for themselves
Your belts always work great and last for multiple blades.
Along with other abrasives, I got from you guys I was able to finish sand this segmented handle beautifully with the finishing belt at slow speed really great product!!
Fits my Grizzly…. shreds grinds, smooth finish👍
Love the durability of the belts, the range of grit is very helpful in the grind and blade process, and handles…the finishing belts are perfect if you are doing farrier rasps or want a satin finish.
These belts are fantastic
Great products
My first attempt to make a puukko knife
The 220 J-flex are great. They make perfect plunge lines and seems to last.
Your belts are the best and I really like the polishing kit I bought
Love these belts! They put a nice edge on this rig I made from leaf and coil springs for a wedding gift. Followed the 400 grit belt with a little stropping and they are SHARP! Excellent belts!!
These are great belts!!!
They are the only belts I use. Teaching my son to make knives, and it's a lot easier when you have the best stuff to work with.
Great belts great service.
Good belts!
Great belt, did a nice gob polishing.
Lasts 10x as long as any other comparable product and tracks better also.
It cleaned up all the grind line and made the blade you see all nice and clean and shiny.
Good belts and they worked as expected. Fair price and great customer service.
I love the belts so far! I’ll continue to use Combat Abrasives for all my knife making belts!! 👍
I prefer using Combat Abrasives. Price is a great match. I have used the more known cubitron and trizact belts and yes, they last longer but the amount that I go through with my business it still is cheaper to buy a three pack from here as the other more popular brands last about the same time as 2 belts from here. More bang for the buck here. I will only ever use Combat from now on

I purchased an assortment of belts for my new grinder, including a few conditioning belts and have made a few knives already on the same set , these belts are a lot more durable than I expected
Haven't used the first belt a whole lot, yet, but it has worked nicely on some wood smoothing projects.
Great product ,always prompt service.
The best grinding belts that I have ever used! Long life and gets the job done 10x faster than others!

These belts fit and work great. Combat Abrasives has become my new choice for future sanding belt purchases.
You guys always deliver good product. Shout out to Black Bear Forge for recommending you!
