Abstract: A hand sanding block is formed with two blocks, which may be of equal or unequal lengths, of like cross section and disposed in coplanar relationship with opposed inner ends. The blocks are freely movable towards away from each other, event to the point of total separation, by means of a pair of spaced dowel pins projecting from one block for telescopic engagement in corresponding spring loaded sockets in the other block and are normally held apart in spaced relationship by the springs in the sockets. For mounting and removing an endless sanding belt or an abrasive sanding strip, the blocks are pressed together so the inner ends are in abutting relationship and once the belt or strip is in place, the holding pressure is released so the block can move apart to provide tension on the belt or strip.

Abstract: The present invention is a swim fin equipped with extendable knives which can be used by a diver to fight off an attack by a predatory underwater creature, such as a shark. The knives, when in their locked closed positions, lie in a recessed section provided in an outside edge of the swim fin. In their locked closed positions, the knives lie parallel with a bottom surface of the swim fin. When extended to their locked open positions, the knives point downward from the swim fin. The swim fin is provided with means for locking the knives in their open and closed positions, unlocking the knives from their locked open and locked closed positions, and moving the knives between their open and closed positions.

Abstract: A carpet trimming tool is disclosed for trimming edges of two carpet sections to be placed into abutment and joined together by a thermo adhesive tape or the like. The device utilizes a base with a pair of transversely spaced, upwardly projecting blades cooperating with a downwardly directed clamping arrangement holding the two carpet sections in engagement one with each of the two blades. Since the two blades cut the respective carpet sections from the underside generally cutting only the base of the carpet, and due to the constant spacing between the two blades, the resulting joint is virtually entirely concealed as there is no damage to the tuft caused by the cutting.

Abstract: The invention is directed to a twin-head shaver comprising a first hinged frame arranged in the shaving head frame and carrying the upper cutters, for control of a parallel relative movement of the upper cutters in the vertical direction, and a second hinged frame for the sequential control of the lower cutters operatively associated with the upper cutters.
