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

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

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.

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

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

Effortless keeping my chisels supersharp.

This works really well, dry or with lapping fluid. I dont know what else to say other than this stuck well, cut well, and left consistently sharper edges than I have ever gotten with my stones and strop. As long as you dont accidentally slice one, they last a good long time too, especially as you get into the finer grits. I wish it were a more permanent solution (like stones) where you are only buying once, but this has such an array of grits that even as I add more stones to my collection, there will still be some levels of fine that I can less expensively get with these sheets.

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 almost as good as stones. Will buy again.

I use these in combination with some glass to sharpen my chisels. These work really well for the moderate and fine steps. Id still recommended a coarse diamond stone for major surface flattening.
