Abstract
Abstract Disclosed is a knife with lighting fixture which mainly consists of a pair of cases, a pivotally turnable knife, and a pivotally turnable supporting plate. The supporting plate has a cell, a bulb, and a push button supported thereon. The push button is slightly projected from one of the case so that a depression of it may lighten the bulb to shine toward the knife for convenient use in a dark place. The supporting plate may be easily turned out of the cases for mounting a new cell and/or a new bulb when necessary.
