Review on 3M 03064 Trizact Performance Sandpaper by Jon Thompson

I glued a spacer onto a small piece of pine and use it as a strap to keep my knives razor sharp. Works like clockwork. I haven't changed the gasket yet so I don't know how long it will last. I've been using it for more than a month, the effect hasn't lost. Wipe gently with a soft, dry cloth to remove darker metallic deposits. I use it like a flat leather strap, but it's important to use very light taps and not enough pressure to compress the foam base. It definitely polishes the edges. DO NOT USE THIS FOR POGS OR MACHINES. They lose their necessarily straight edges.
