Very useful and effective polishing paste. We put it on a strip of leather that was attached to a long piece of wood with a staple gun. 10 strips per side will fully polish any blades (e.g. carving knives) newer than mine. The result is a clean and sharp cut of wood or paper. I've been using it for over a month now and have barely used it. Looks very durable and economical. Highly recommended.
