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

Like the adhesive back, disappointed by the durability. Might work well for touching up chisel or plane but I was touching up heads and didn’t hold up

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.

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.

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.

Perfect for sharpening chisels.

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.

Works great

Received as advertised. Good experience.

A ideal part in honing straight razors allowing tremendous versatility.
