A froe is a tool for cleaving woo by splitting it along the grain. A froe is used by hammering its blade into the end of a piece of wood in the direction of the grain, then twisting the blade in the wood by rotating the haft (handle). A froe uses the haft as a lever to multiply the force upon the blade, such that it possible for wood to be torn apart by even a small froe with remarkably little force applied to the haft.
