Review on 3M 03064 Trizact Performance Sandpaper by Marco Maurer

Cool! I use it for both knife polishing and blade sharpening. Wow I can't tell you how well it works for this purpose. It removes some metal, but much less than a stone but more than a leather belt. It's built on a foam base that appears to "hugg" the edges. For knife sharpening, this means it's much more forgiving with the angle you use. Even if my angle deviates slightly, the foam automatically compensates for this due to the deformation. In terms of durability, even after 5 knives of sharpening the edges and polishing the ends, it still looks brand new. I will DEFINITELY buy this again.
