These are 8″ long and 1/4″ thick and are made of solid titanium. They come standard with blunt edges. To use these, you simply attach the loop of the leader to your dive float or belt and string the fish using the rod. You can go in one eye and out the other eye, or through the gills and out of the mouth. The rod prevents the fish from slipping out. Its a very simple and efficient way to keep fish. They can also be used as regular fishing stringers. These work very well for braining fish too.
