Thumb Chuck - Hardcore Compatible

I designed some thumb chucks heavily inspired by Jimpy Designs which will fit Aroundsquare hardcore-system gut beads. Tested with Newton and Herc cores. The bore that runs the length of the shaft should be wide enough to slide 550 paracord all the way through from the top without trouble but I'd still recommend an angled cut and a cleanly melted end to make the stringing process go smoothly. Enjoy!
