Abstract: An improved surgical fastener of the type used in a surgical applicator which has been modified to enhance the gripping capability of the fastener once secured. The fastener can have apertures therethrough or the surface can be knurled, crimped, etched with a laser, layered with an abrasive coating, sand blasted, punched, notched, or modified in any other manner which enhances the grip of the fastener when secured. Additionally, the fastener can be formed from or coated with a magnetic material, which provides additional holding power to maintain the clip closed after it has been secured into the tissue. An alternate embodiment includes a double wall to reinforce the fastener when secured.

Abstract: A golf club, such as a putter, utilizes removable shafts, removable weights in the shaft grip end, a variable length adapter to connect the shaft to the putter head and vary the shaft end weight, and removable weights in the putter head to vary the pressure of the putter relative to the putting surface speed. The putter head also includes weighted inserts or plugs placed in the head during manufacturing to vary the weight of the putter head. The striking face has an additional insert at the striking point adapted to receive various types of plugs to vary the percussion response. Grooves on the top surface of the club head provide improved "sighting" of the golf ball in relation to the hole. The club head shape and grip end appearance remain unaltered and thereby retain user familiarity and confidence.

Abstract: A golf club, such as a putter, utilizes removable shafts and weights to vary the pressure of the putter relative to the putting surface speed. Alternative embodiments affix the shaft with a whistle stop notch or a conical wedge. Various strategies for detachably retaining weights in the club head are shown. The club striking face and club head appearance remain unaltered and thereby retain user familiarity and confidence.

Abstract: A golf club, such as a putter, utilizes a removable shaft which is attached by threaded members extending axially of the shaft. The threaded members can be of varying weights to vary the pressure of the putter relative to the putting surface speed. Alternative embodiments affix the shaft with double threaded members.
