The SpoolTek™ concept of leader concealment involves housing the braided wire leader on a small internal spool inside the lure. In the case with the SpoolTek lures, there is a hard, front section and a replaceable, soft plastic tail section. The internal spool is inside the hard front section. The leader is approximately 12 inches long and is easily reloaded onto the spool with the ‘thumbwind’ knob at the top edge of the lure body. The leader can be wound on with one finger or with your thumb and forefinger, and it can be wound or turned in either direction.
