Abstract
A knife for personal use has a liner made up of a pair of parallel walls spaced apart along a transverse axis at right angles to the longitudinal extent of the walls. A hollow hub extends along the axis and abuts bearing surfaces in the walls and also abuts a bearing surface in a blade disposed between the walls. The hub has at least a first notch extending radially of the axis. A second notch in one of the walls extending radially of the axis is adapted to register with the first notch. A third notch in the blade is adapted to register radially of the axis with the first and second notches. A thimble-like detent is mounted for axial movement relative to and partially within the hub. A key projects radially from the detent and has an axial extent effective in one axial position of the detent to lie wholly within the third notch and in another axial position of the detent to occupy a position lying within the second and third notches simultaneously. A spring preferably housed within the detent and the hub urges the detent into a projected position.
