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

I purchased these to use with my Worksharp knife sharpening system. I cut them to fit the stone and then just put them on. I get a razor sharp edge and a mirror polish. Very happy with this lapping film.

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!

Used a large granite cutting board to put 6 on one surface. Adhesive is great. I can now hone my tools to razor sharpness in a seconds. Dont know about the durability yet.

As advertised.

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

Not worth the money

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

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

I love 3M the best for sharpening!

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.
