18 PCS 1 x 42 Inch Silicon Carbide Sanding Belts Assortment- 80, 120, 240, 400, 800, 1000 Grits Premium Sander Belts For Knife Sharpening and Metalworking

The 80 grit worked great for sharpening a 21 inch lawn mower blade. The edge was dull but it's nice and sharp now. I don't see any wear at all of the belt. Sharpening was fast too. Belt ran smooth and I didn't notice any difference where the belt slice is. Tracked well. I can't wait to try some of the finer grits on knives and shears...

Excellent for the knife maker! Don’t sleep on silica carbide. It’s better than aluminum oxides and for the higher grits, it cuts fast and wears well. I use these for finishing up to 400 grit and then move to hand sanding or surface conditioning belts. They do get hot and dusty, so use water and clean them with a rubber eraser often. Won’t replace ceramics in the low grits obviously. Best for finishing and handle work.

Haven’t used them too much but what I have They seen to work well and stand up to The buffing and sanding our I was doing with the belt

Great for knife sharpening. Although I always finish with wet stone

I had a dozen of Gator(made in the USA and yes, cost much more) but they didn't last long at all. Some days, I went through 2-3 of them easily because the sim always broke off.So far, the silicon carbide (3 of them in use) are hanging tough and still work well. Money well spent!

Good quality

Very happy with the sander belts. Different grades for different projects. Work well cutting the rough metal and fine belts smooth and polish.

I've done a lot of sharpening. I started with whetstones. I mastered those to the point where I could get every single knife I touched hair whittling sharp. As I sharpened more and more, I realized it was taking forever. Flattening the stones, soaking them, increasing the grit, all took forever.So I transitioned over to a diamond stone. This was better as diamond stones abrade much faster than whetstones. They also need almost no maintenance. No need for flattening or soaking. But it was still a lot of manual labor and if I just sharpen with 1000 diamond it took about 2 to 5 minutes. There had to be a better way.After researching the many devices available including electric sharpeners, machines like the tarmac, jigs like the wicked edge, etc. I finally decided on a belt sander. I didn't want to pay a lot of money, and I wanted a flat edge (not concave or convex). I figured a belt sander is basically a stone but it moves on its own. So I bought one of those 1x30 belt sanders for around $60. For months, I've been using the belt that came with the sander. It's about 120 to 240 grit. I could get knives sharper than brand new ones to the point where they could shave arm hair (not cleanly and face shaving was very uncomfortable) within 1 minute. But I was never really happy with the results. I thought people were right when they told me that an edge from a belt. Sander was not as good as he whetstone.But these belts changed that. I immediately tried the 1000 grit belt on my already pretty sharp knife. The difference was immediately noticeable. I could cleanly shave all my arm hair in one pass and I could even semi-comfortably shaved my face. The belt construction even though it seems thinner than the Harbor freight belts, the gluing seems to be a lot better. The Harbor freight belts have a bump where the seam is and it causes a lot of vibration and it slightly pushes the knife away from the platen on each rotation. The 1000 grit belt was very smooth and very quiet. The only bad thing I noticed was after only two or three sharpenings, I noticed there was significant wear on the edges of the belt. I could see the white paper backing where the grit has completely worn down. I've used the Harbor freight belts for about a dozen sharpenings and re bevels with no signs of wear.I will definitely be looking for even higher grit belts. I'm very happy these belts helped me discover a better way to sharpen.
