Lapping Microfinishing Film with PSA - Set of 8 Polishing Sheets 4.25’’ x 11’’ for Scary Sharp Sharpening System - AO Aluminum Oxide with Pressure Sensitive Adhesive

Only lapping films I use at my professional sharpening business. Affordable, good size, and great performance. Good mix of cutting aggressiveness and durability. Adhesive is strong.

I bought these almost on a lark to try polishing some small glass lenses that I figured were otherwise totally done for. Given the low price of this film, I wasn't really expecting much to come of it, but I figured I had nothing to lose by trying.The results were way past my highest expectations. I was able to restore my scratched or even totally chipped lenses back to a mirror finish and perfect clarity.This lapping film should work perfectly for polishing optic fibers, or anything where the glass surface needs to be flat. The film is fairly stiff, so I don't know that you could get good results trying to polish something very round, but for optic fibers, perfect.The adhesive backing was also very helpful; I was able to cut some strips off of the film and adhere them to a small pane of glass, which gave me a really nice, flat polishing surface. Using that technique, I think I'll be able to stretch this film for quite a few uses, and given that the full sheets are pretty cheap to begin with, this product is shockingly affordable.

This and a glass blank from Gritstone,I quickly trimmed 1"strips and they adhered well to the blank,I spritzed the film and put that $100 mirror finish on my 1st blade.EZ-Z

I attached these to the ceramic Blades of my knives. I'm very happy with the overall quality and these will probably last me a lifetime. I get all of my knife blades sharpened to a mirror finish

Work’s great for stropping. Helps get my blades scary sharp.

A good tools sharpening system. One piece of glass is good 3 would be better. Takes you through 300 grit through several finer grits. Would recommend picking up a couple of courser grits if you're sharpening up used or older tools. Gives you a mirror finish and a very sharp edge.

I'll admit, I was exceptionally skeptical about how well this set of lapping films we're going to perform but, they work extremely well on any guided sharpening system. I wanted something faster and easier (other than my old method of using automotive wet paper adhered to ceramic stone) to achieve a nice mirrored edge on my EDC folders. Using theses films in succession along with a set of Jende 1"x6" nanocloth strops (.25 micron, .10micron, and .025 micron) on my TS-Proof guided system gave me some insane results so far. I've done 3 knives so far and I'm getting lower BESS numbers (best so far is 64 BESS with my Shiro Quantum) with those 3 knives than I'm getting with a fresh utility blade. I love these lapping films and will certainly be buying more. can't wait to see what I can do on some on my thinner bladed knives like my kitchen knives. Definitely recommend to anyone wanting to achieve that next level edge on your knives. Will adhere to any ceramic stones on any guided sharpening system.

Okay so came across this and wasn’t even looking for it but I thought I would try It out and I will say this that I will not be buying any other lapping films other than these they are perfect you cut to size you need and that’s it you get a beautiful mirrored edge on everything you sharpen and the price is the best part
