The molded design allows for perfectly radiused edges that dont nick or weaken rigging bands. It also allows the perfect and consistent clearances needed to retain the R&R rigging bands. The needle is also designed with friction pads for easy grip as well as slightly flattened sides that keeps the needle from rolling off work areas. A very sharp two blade micro tip allows for an easy penetration of hard tissue when bridling baits. These needles are corrosion free and do not deteriorate in saltwater.
