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

So far so good with these, Ive used them to polish/hone some straight razors to try this method out. I prefer an actual stone though after trying this but then again this isnt what these sheets were designed for so they get 5-stars from me for their quality.

These films work well when used with flat substrate, though the finer films are easily cut unless care is taken to use only pull stroke. Coarser films OK for back &forth grinding.

Works like a champ getting that extra edge of sharpness

Just what I needed for a great Christmas

I got this along with a piece of glass because I’ve been trying to hone my straight razors. I have a slew of shapton stones, norton, naniwa, chromium oxide to apply to my strops, and I’ve never been able to get a razor to the point I liked it. That was until I tried this stuff. I kept the backing on and just put it on top of a wet piece of paper on top of the glass and it was amazing. The edge that I got was extremely clean, even when looking at it under magnification. I’m not saying that these are better than stones, but they are much cheaper of an initial investment and for someone new can give you a very good result. I was ready to give up on honing myself but this has rejuvenated my enthusiasm. I’m excited to learn more and continue in this adventure now.

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.

better than diamond stone

Not what I was expecting.

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.

Great item
