A locking button mounted in the socket is movable between a locking position (to which it is biased) at which a slightly tapered locking portion of the button is in engagement with walls defining the larger portion of the aperture to lock the blade in the attaching assembly; and a release position at which a narrow portion of the button is aligned with the slot so that the blade can be slid into or out of the slot with walls of the blade defining a narrow portion of the aperture communicating with an edge of the blade sliding past the narrow portion of the button.
