LSPK; The Lansky Puck is a two sided artificial stone for sharpening axes or other large tools. When sharpening large tools it's more convenient to move the stone on the tool. The stone is about 3" in diameter and 1" thick. The sides are beveled for a comfortable grip. One side is coarse (120 grit) for removing nicks, etc., and the other is a medium grit (280 grit). Made in the USA.
