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

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

There is no marking on the sheets as to which grit each sheet is.

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.

Excellent product very durable just a little pricey

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

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

The finer grit Lapping Paper lost some of its surface when I was sharpening my chisels. This only happened on the two finest grits. The abrasive surface would completely rub off the paper, as if I was scraping it off.

Not quite as durable as I would like for sharpening chisels and plane irons. However they will put a seriously sharp edge.

good quality and good seller

I like the polish on the end results of my chisels and plane irons. I am not happy with the jump from 1,800 to 8,000, but I have a 5,000 gray PSA sheet still laying around to fill in the gap. I applied the PSA to flat 12 x 12 x 1.5 peace of granite for all my chisels and plane irons lapping. I touch up all the edges on a 10,000 grit water stone. I like the PSA on granite because is stays flat, not like my water stone that dishes really quick. Yes I flatten my water stone often with a lapping plate. But lapping is boring and the PSA on granite just makes it full proof for a flat surface.
