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

Great item

These work great for getting a mirror polish on a knifes edge

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

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.

Works great

I bought these sheets after watching a YouTube video of someone cutting them to size and sticking them to the ceramic hone on a Worksharp Precision adjust knife sharpener. I cut them into sight oversized strips and they adhere perfectly to the ceramic. Knives come out shaving sharp with a mirror finish. You can get multiple uses out of the strips if you stick them to a piece of wax paper to prevent the adhesive from drying out. I can sharpen about 4 pocket knives 3-4” blades using the strips before it’s time to change strips. I got about 14 strips out of each sheet of lapping film. If you do bigger knives they obviously will wear out more quickly. Pull the paper with the cutting edge towards the apex, don’t push the paper into the cutting edge or you will slice it. I also buff side to side and it doesn’t cut the paper, and finish with 10 strops along the knife blade from hilt to tip on each side and finish with 50 strips each side on the 60,000 grit white film. This stuff is awesome and I will be purchasing more when I need to.

Not good for honing straight razors. Pitched in the garbage.

Mounted to pieces of glass and have been great for sharpening all kinda of tools

I cut them down and stick them on the ceramic piece in the kit. When done I stick them to a plastic sheet and get several used out of each one. You can put a razor sharp mirror edge on your knife.
