Replacement harpoon tip reinvented.
We've thrown out the standard stainless steel aircraft cable and replaced it with spectra. It's easier on the hands, flexible yet abrasion resistant, will promote less tear out of meat, and it's stronger. The eye is bigger to allow you to use your existing harpoon line w/buoy set up but the 12/0 swivel was removed in favor of a 6/0 swivel to allow the tip to be attached to a fishing rod.
Used on harpoons with a 3/8" shaft or smaller.
