  • Patent number: 11458596
    Abstract: A clamping and locking device that uses two main parts. The two parts are connected by an axle, which acts as a fulcrum. The assembled clamp has jaws that meet together on one end of the assembled parts. There is a multi-radius latching system on the inside of the handle arms located on the other side of the axle. The handle arms may be straight or curved. The ends of the handle arms can be straight, or have hooks, ring-holes, hand-grips, or an assortment of other useful end-of-handle designs.

  • Patent number: 7653976
    Abstract: A repair kit for fishing rods that has a replacement tip and a coupler to repair the shafts of the broken rods. The kit can be carried in the field as part of regular tackle box. The replacement tip is a formed body that has a threaded end. The ferrule is formed as part of the body so that is not susceptible to breakage. The ferrule can be also lined with a ceramic eyelet that reduces friction on the line passing through it as well as adding strength. The coupler is a two ended-part that has two formed tapered threads or two formed metal inserts inside the coupler. The coupler is twisted onto the end of the broken rod until it is secure. The other end of the broken rod is then twisted into the open end of the coupler. Once the second end of the rod is secure, the rod is again ready to use.
