A bladed tool holder has vertical, elongated blocks spaced laterally from one another far enough to accept between them a blade of a tool to be held. The blocks have facing surfaces one of which has a sloping seat, opening toward the facing surface of the other, the seat sloping away from the other surface in a vertically upward direction at an angle preferably between 12 and 15 degrees. A ball, preferably of matte finished polypropylene, of a diamter to permit the ball to move freely in the seat but to project from the seat at the lower end of the seat, is mounted in the seat. In a holder for chisels and the like, in which the narrow side edges of the chisel are held between the ball and the facing surface, the ball is caged in the seat to preclude its falling out. A cap, bridging the space between successive blocks on the chisel holder, serves several functions, including protecting the sharp edge of the chisel from damage and protecting the user from injury.
