7 Sheet Variety Pack PSA Pressure Sensitive Adhesive (.3, 1, 3, 9, 12, 30 and 40 microns) Lapping Microfinishing Film Aluminum Oxide (AO) 8-1/2 x 11 Inches

I got these to cut into strips for my worksharp knife sharpener. Needless to say they worked well and make for a really nice edge!

I happened to have a big piece of flat glass and was able to stick a half sheet of every grit to it and sharpened every chisel and plane blade I have to a scary sharp edge.

these are okish, they do the job but not better than a cheap stones. i did manage to get a very good mirror bright edge but did not find it easier or quicker than stones. i would imagine that any one reading this is already a sharping snob, so no this will not take your sharping to the next level, and no this will not replace your stones, no they are not much better wet/dry sandpaper you pick up from the auto parts store. in summery if you want to try something different, or have no other way to sharpen they yes these will work for you, but with 3 plates of float glass and costing a total of $59.98, there are much better ways to go about it. Quick tip, make sure the edge of the film lines up with the edge of the glass, if you sharpen a knife with a bolster you will not be able to sharpen all the way to the base of the blade

These are great. Very easy to use one you know the proper technique. They produce an absolutely stunningly sharp edge on the chisels, planer blades, and knives I sharpened

Nice price on this wide variety of lapping films. Puts a keen edge on razor and knives.

Excellent product very durable just a little pricey

Perfect for sharpening

These are almost as good as stones. Will buy again.

I am very pleased with the purchase of my 7 Sheet Variety Pack PSA Pressure Sensitive Adhesive Lapping Microfinishing Sheets. It gives me the ability to produce a very fine edge on my woodworking tools. From my experience to date with this product, I am getting as fine an edge as I would with sharpening stones. I use the PSA Sheets on a large piece of safety glass and have all the grits on one surface.

These are pretty good lapping films. Puts a mirror polish on most metals.
