Casing spear
Casing spear is a tool for fishing internally.It has features of simple operation, high strength, large grapple area, wide fishing range. It can be used individually, and aslo can be used with cutting tools to finish cutting and fishing at one time. If the fishing work is not successful, tools can be easily release from the fish.
