Abstract

See full text

An improved utility knife with an ergonomically shaped handle having a cavity and a working blade holder slidably disposed within the cavity is described. A bottom release lever and a top drive lever are pivotally mounted to the handle and movable with respect to the handle for releasing and moving the working blade holder, respectively. The knife includes an extra blade holder slidably mounted to the handle and movable with respect to the handle within the cavity. The extra blade holder includes a front support end for engagement with a working blade, whereby slidable displacement of the extra blade holder disengages the support end from the working blade to allow removal and replacement of the working blade from the utility knife.
