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

Not what I was expecting.

They were shipped as promised, will allow me to make 11 sets of each grit, the only problem I noticed was the light green sheet was cut to 3-3/4 not 4-1/4

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 got this along with a piece of glass because I’ve been trying to hone my straight razors. I have a slew of shapton stones, norton, naniwa, chromium oxide to apply to my strops, and I’ve never been able to get a razor to the point I liked it. That was until I tried this stuff. I kept the backing on and just put it on top of a wet piece of paper on top of the glass and it was amazing. The edge that I got was extremely clean, even when looking at it under magnification. I’m not saying that these are better than stones, but they are much cheaper of an initial investment and for someone new can give you a very good result. I was ready to give up on honing myself but this has rejuvenated my enthusiasm. I’m excited to learn more and continue in this adventure now.

I used this product to finish sharpening a new set of chisels and tune up a couple of my hand planes I used a diamond sharpening system then the finest grits using this system. They turned out great. I could see my self in the surfaces

They work great with my wicked edge glass blanks.

Polished a L max blade. Worked as advertised. Just pour delivery.

This is what you need if you are using it to sharpen along with a honing guide. Managed to get a great and sharp edge to a well used second hand plane. Works for chisels as well.

Great item
