Why didn't someone think of this before? The original BeadSmart Thread Burner by EURO TOOL is perfect for stopping frayed ends of thread on embellishments, peyote stitch or anywhere raw ends need to be eliminated. Cuts and cauterizes! The tip heats to red hot at the touch of a button and melts synthetic threads so that they don't unravel. Powered by one AA battery (included). The Perfect End Thread Burner is reasonably priced and the ultimate tool for bead stringers. Replacement tip also available, here.
