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

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.

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.

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.

A ideal part in honing straight razors allowing tremendous versatility.

Using these mounted on an aluminum plate for fine finishing on S30V and M390. They stay on the plate well and are removed easily in one piece. The papers do sharpen and polish as expected for their respective grit but do seem to wear out quickly. I would tell others to expect one grit paper per 3.5 inch blade. If you are looking to progressively move through several grits then plan on using several papers in the set.

I ordered these thinking they were adhesive backed and was disappointed when they weren’t but after giving them a try they do an excellent job at sharpening and putting a nice near mirror finish on any metal. And with a bit of stropping with polishing compound I was able to easily shave the hair off my arm

I ended up buying shapton stones because the money I would need to put into buying more of these did not make sense. I would be happier if I received all the correct grits as advertised.

Great product. Sticks to glass beautifully. Will buy again when needed.Really gives a sharp edge.

Don’t waste your money. Buy diamond lapping films. These things do not work. I’m a professional knife sharpener. Highly disappointed

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.
