3M (TM) 7 Sheet 4-1/4 inch x 11 inch PSA Lapping Microfinishing Film For Scary Sharp Sharpening System Aluminum Oxide AO

Works like a champ getting that extra edge of sharpness

They work great with my wicked edge glass blanks.

The adhesive backing on these super fine abrasive sheets allow you to attach the to a smooth rigid surface.

Get a guide and put an edge on your plane iron and chisels like no other. After a while the adhesive comes loose but no big deal.

A ideal part in honing straight razors allowing tremendous versatility.

Sheets work very well. Problem is durability and quantity. Most will never need all 9 films, youre better off buying sheets of 9x11 in grit needed. You can also get Diamond film from KME which lasts way longer. KME gives you five 4x1 slabs which last about 5+ times longer. These are nice due to size but dont help me. When using KME these sheets will get you through 1 maybe 2 knives that need moderate work. The KME ones will get you through 7 or more as they are diamond. ALWAYS remember to hone away from edge if you push towards edge you will cut film and ruin it. If using KME system you will need a glass blank for film(or alum/glass blank) for backing. The film removes better from glass

I bought these to see how well they could do for getting a mirror edge on my Spyderco knives with my KME. So far not bad, I cut strips to fit on my glass slides like my diamond tape and so far so good. While not as good as my diamond tape, for the price its very good. I would buy them again.

Nice adhesive, durable backing, nice grit selection. Will definitely purchase again in the future.

Don’t waste your money. Buy diamond lapping films. These things do not work. I’m a professional knife sharpener. Highly disappointed

Only went 4 grits in and then accidentally cut off a little translucent layer of skin with the chisel. That was good enough for me to stop there lol. Also careful doing sharpening by hand. If you use your finger to feel for the bevel and it touches this stuff youll burnish you skin before you know it!
