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

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.

Used to sharpen a straight razor with incredible results. I only used the 8k grit paper and stripped the razor. That was enough to take the razor from tugging terribly out of the box from Dovo to a buttery smooth shave

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.

For sharpening my knives, I use a wet stone and a leather strop. I was content with the results but I knew I could get them sharper. Watched a video and thats what got me interested in these. Using these to get that final polish on my knives has made a huge difference.

Not good for honing straight razors. Pitched in the garbage.

Works great

Great product. Use it for polishing knife blades.

I purchased these to use with my Worksharp knife sharpening system. I cut them to fit the stone and then just put them on. I get a razor sharp edge and a mirror polish. Very happy with this lapping film.

Polished a L max blade. Worked as advertised. Just pour delivery.

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.
