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

Works like a champ getting that extra edge of sharpness

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.

First time using this product to sharpen a straight razor. Worked very well , hard for me to tell when it’s worn out.

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.

They work great with my wicked edge glass blanks.

Not what I was expecting.

Love how easy it is to use and how quickly it was once I figured the order is backwards on using the guide. Learning how to sharpen my knives properly on a guided system but lapping films have made a difference on my gentleman knives!

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.

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