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

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

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.

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!

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

Only went 4 grits in and then accidentally cut off a little translucent layer of skin with the chisel. That was good enough for me to stop there lol. Also careful doing sharpening by hand. If you use your finger to feel for the bevel and it touches this stuff youll burnish you skin before you know it!

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

I love 3M the best for sharpening!

Great item

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.

Perfect for sharpening chisels.
