The electric Jaw Saw is a terror for wood but safe for the person who is using it. Its metal jaws leave only a small amount of its the chain exposed lowering the risk of contact with the user’s body as well as preventing kickback and chain damage when it’s sawing things on the ground. The steel teeth can lock onto a piece of wood of up to four inches in diameter to increase stability while the chain rips through it.This is going to be a useful tool for construction workers.
