Cutting tool
A cutting tool includes a rotary blade driven by a motor, a fixed blade disposed opposing the rotary blade, a housing holding the motor, and a battery mount part on a rear portion of the housing. The battery mount part has a guide groove that slidably receives a rail of a power tool battery pack. A blade cover is disposed partially around the rotary blade, and a portion or all of the blade cover has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade. A base holds the fixed blade, and a portion or all of the base has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade.
