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

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

Product is good but, after buying over 100 packs, I can say with a lot of experience that the quality control on the cutting is terrible. Often getting sheets that are 1/2” off in width sometimes and not cut straight. Don’t get these if you need them to be precise in size.

A ideal part in honing straight razors allowing tremendous versatility.

These work much better than sprays adhesive on sandpaper then applying to glass for sharpening chisels and planes. Easy to apply and just the right size.

I love 3M the best for sharpening!

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.

I collect and (try to) restore old vintage Western of Boulder Colorado knives which have carbon steel blades that tarnish, patina and pit if not properly cared for. I use these to - by hand - polish out the imperfections and bring the blades back to a luster. Not always a mirror perfect finish based on the starting point condition, but these do a pretty good job. Its hard work but keeps me sitting at my bench for hours and off eBay for a while! I dont stick these to glass or adhere them to anything. I cut small patches and use my fingers to polish with.

So far so good with these, Ive used them to polish/hone some straight razors to try this method out. I prefer an actual stone though after trying this but then again this isnt what these sheets were designed for so they get 5-stars from me for their quality.

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

Im used to using files and wet stones. Decided to try this for my wood chisels. They are scary sharp. Easily shaves hair off my arm an slices through wood with little effort, which gives greater control. Wish I would have switch to this when i first heard of it.
