Excellent!
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.

Crazy good deal at 8 bucks on prime day!
Great deal in prime day for 8 bucks. These aluminum oxide PSA sheets are great for polishing. The durability of these sheets is excellent so long as you watch what your doing and don't cut them on edge leading passes. The ease of use is excellent due to them being PSA backed so it's stick and go and they peel back up easily and restickable with no issues. The varieties of grits are excellent for a full progression to a High polish at 3 tenths micron.

Inexpensive Intro to tool sharpening
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.

Why pay More? These get the job done much cheaper, Trust me. ๐๐ป
Works great at a fraction of the cost of my KME Sharpener film kit. I just wish the grit was printed on the sheets themselves.

Works super well with any guided sharpening system
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.
