Abstract
A cutting tool includes a blade assembly with two retractable, opposing blades in a handle shaped for comfortable gripping. The blades may be closed and stowed by being partially retracted into the handle with a continuous motion of a single hand. The blades may similarly be extended and deployed for use with a continuous motion of a single hand. Each blade is formed with a shearing edge and a lever arm. Each lever arm is formed with a slot for engaging a blade locking tab joined to a cover for the handle. When the blade assembly is retracted into the handle, the shearing edges of the blades remain safely closed when the lever arms are released by a person using the tool. The cutting tool includes a retractable tether for preventing loss or damage to the tool should it be dropped.
