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

The lapping paper I received was not a PSA backed paper it was just a fabric backed lapping paper. Not impressed with getting something different than what was listed.

I ordered these thinking they were adhesive backed and was disappointed when they weren’t but after giving them a try they do an excellent job at sharpening and putting a nice near mirror finish on any metal. And with a bit of stropping with polishing compound I was able to easily shave the hair off my arm

As advertised.

Love 3m products. I use small chisels on a daily basis and these true up an edge really well really quickly! Must have in addition to your glass or stone.

Great item

Used this with the worksharp sharpener. Used it then threw a slit of that light green paper on it and in no time was able to slide hairs right off my arm, would definately recommend. Since the light green is one of the smaller grits this means i can go sharper, but this is great for what i need.

Works great

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.

better than diamond stone

I was skeptical at first, but this stuff is a lot easier to use than regular wet sandpaper. It comes with a huge assortment of grits, really more than is needed. Id rather just have 2 sheets each and half the assortment. Its tough to tell the grits apart, so keep track of the colors and mark each one. It comes with some printed info too (see pic). Originally mine showed up with this bit of odd staining but they quickly sorted it out.
