Abstract
This disclosure pertains to a handle, housing a battery and a switch and is adapted with a removable blade securing bar extending transverse to the longitudinal axis of the handle. A plurality of blades are removably engaged within a series of spaced apart notches in the bars. A lamp is secured to the handle providing a convenient work light covering the area that includes a series of blades extending parallel to the longitudinal axis of the handle when the blades are secured within the notches. Each blade is adapted with at least one cutting edge and may be secured to the bar with the cutting edge extending in a preferred location, thus enabling the user to select either of two types of cutting edges or to position a variety of cutting edges of the adjacent blades in a cutting work plane and to position the blades selectively in the notches, providing thereby a variety of cutting widths.
