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

The performance at putting very polished and fine edges on knives is superb. I use these free hand on glass plates and I also use them on a TSPROF fixed angle and a Wicked edge fixed angle. IMHO the only ones of use are the 9 and below micron, the 30 and 40 to me have zero use. They are very good for putting a very fine edge and for getting a near mirror finish on the edge bevel that with just a slight bit of stropping will be a bright full mirror finish. The down side to them is on super steels like S90V, S110V, M390, S45vn etc etc you will wear them out like crazy. Trying to get that mirror finish. Now on steels like 420/440, 1050/1070/1095, AUS8/10 VG10, Cts BD1(N) and the likes you will get a couple knives off a 5.5x1 inch set. On the super steels I would say you would be lucky to get one knife off a set if you cut them 5.5x1 inch like for the wicked edge. Im mainly talking about the 3, 1 and 0.3 micron films with the wearing out really quick on the really high carbide high speed tool steels. If your just sharpening more of your normal alphabet soup steels (IE 3cr13mov, 8cr14mov etc) or AUS8/10s, 12c27s 440HC etc etc you will likely get two to three knives before the films need replacing. IMHO this are not a replacement of a proper stone progression and then strop progression for sharpening hobbies and knife collectors like my self.. But for your avg guy that just wants to put a very good edge on his knives and dont want to spend 1000s of dollars on high end stone progressions because he dont sharpen knives all that often then these films do a excellent job for that. I use them to keep wear off my really high end Shapton and Venev stones when Im sharpening knives that I dont care all that much about how perfect the edge is but yet want a hair whittling edge on.. These do not take the place of high end sharpening stones but they will allow you to get some mighty fine edges without spending a lot of money if you dont mind how slowly they cut and having to replace them a lot.

Perfect for sharpening

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.

They work great with my wicked edge glass blanks.

Effortless keeping my chisels supersharp.

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!

good quality and good seller

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

Very easy to stick to a piece of float glass without bubbles so long as you follow the tips with washing the glass then wetting the glass first. I had some old chisels that were in pretty rough shape that are now razor sharp. Coupled with a honing guide, these sheets made quite work of each chisel.
