Abstract
Abstract A tool includes a handle having a cutting blade, a writing implement sharpener and spare blade compartment combined in the one tool. One embodiment permits the blade to have an adjustable disposition while another embodiment fixes the disposition of the blade. In one embodiment the sharpener is located at one of the ends of the tool handle while in the other embodiment the sharpener is located at a mid portion of the handle. In the case where the disposition of the blade is adjustable, a leaf spring biases a lug into an indentation and another lug detent into a recess in the blade. The leaf spring slides above the blade between two separable longitudinal halves of the handle. The sharpener assembly is fixedly retained within the confines of the tool body with an aperture in abutting rims of two shells of the body providing for insertion of the implement to be sharpened. Shavings are discharged exteriorly of the tool through a slot formed in one of the body shells adjacent the blade of the sharpener.
