Abstract
A double-ended utility knife having a housing or handle including an elongated, generally rectangular base member with a first end, a second end, a front side, and a back side is disclosed. The front side of the base member has a front compartment and a cover and the back side has a back compartment with a cover where the covers are attached to the front and back sides, respectively. Each of the compartments and covers extends less than the total length of the base member and is located at opposite ends of the base member. Each cover is secured to the base member by its own screw so that only one cover need be removed in order to replace a blade. Blades extend from both ends of the housing and have their own actuator so that each blade may be extended or retracted independently of the other.
