We have taken locking coni-tongs to a new level. We laser cut a different notch to make the gripping much better and easier on/off capabilities. We removed all the outside clutter on the tool and added an internal spring to assure positive lock-up every time. There won't be no jumping past this lock groove. The spring is under the trigger mechanism so it's totally out of the way and hidden so it's not catching on everything and ripping holes in your gauntlets. All locking nuts and bolts, this allows you to set the working tension the way you like it, and it will stay there. Rubber grips, the trigger system is zinc plated and the ENTIRE TOOL COMES POWDER COATED. Ready for years of trap line use, made in U.S.A., and we have added a new stainless locking spring to this tool.
