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

Product is good but, after buying over 100 packs, I can say with a lot of experience that the quality control on the cutting is terrible. Often getting sheets that are 1/2” off in width sometimes and not cut straight. Don’t get these if you need them to be precise in size.

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.

Don’t waste your money. Buy diamond lapping films. These things do not work. I’m a professional knife sharpener. Highly disappointed

Not worth the money

Works like a champ getting that extra edge of sharpness

A ideal part in honing straight razors allowing tremendous versatility.

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

Quick shipping, well packaged, and marked 3M. Recommend

Nice adhesive, durable backing, nice grit selection. Will definitely purchase again in the future.

I cut them down and stick them on the ceramic piece in the kit. When done I stick them to a plastic sheet and get several used out of each one. You can put a razor sharp mirror edge on your knife.
