Abstract
Provided is a hacksaw comprising a front cavity in a tang of the frame, a resilient member having one end fastened in one side of the cavity, a handle for receiving the tang and a top opening aligned with the cavity, a pivotal lock lever disposed in the opening and comprising an arm and an end urging member (e.g., cam), a blade inserted through the cavity and the tang into the handle. A thin portion of the urging member is disposed proximate the resilient member and the resilient member is disengaged from the blade when the arm is disposed in a forward position. To the contrary, a thick portion of the urging member is pressed down on the resilient member for fastening a back of the blade when the arm is disposed in a rearward position.
