This invention relates to knife sharpeners, and particularly to knife sharpeners of a kind which are incorporated in a holder for the knife in which the knife is placed when not in use. In such holders the blade sharpener is located so that the action of positioning the knife in the holder, and/or the action of withdrawing the knife from the holder, moves the cutting edge relative to the sharpening device to effect a sharpening action. The knife sharpener of the present invention is provided with means which are incorporated in the holder for varying the effectiveness of the sharpening device even to the extent of rendering it inoperative.

Pruner

The hand tool comprises two members, for example male and female blade members in the case of a garden pruner, each formed with a tang portion which extends within a handle. For locking the members in a closed position a catch pin unit is fitted to one of the handles; the unit comprises a catch button secured slidably to a mounting plate by engagement with a spring plate on the opposite side of the mounting plate. The spring plate has resilient fingers which hold the spring plate releasably in selected positions. A catch pin which engages in the catch button is movable thereby along a slot in the associated member into and out of a recess in the other member to lock or release the members. The members are releasably secured to the handles by a pivot bolt which passes through registering apertures in each member and associated handle. A recess in a said tang portion forms a seating for a stop cushion which extends to the surface of the handle through an opening in the handle above the recess.
