The sharp tip of this acute-angled blade ensures efficiency and is perfect for cutting delicate or curvy patterns from thin materials. With its blade tip held in place by an ingenious position-restraining mechanism, this inverted triangular-shaped cutter promises utmost stability, controllability and cutting performance. Based on a fair amount of user behavior observations, SDI came up with the most maneuverable design for all users, whatever their grip. Moreover, a tiny opening near the tip allows convenience- and safety-minded users to quickly sever threads without sliding the blade out of its dispenser.
