NT CUTTER A300R plastic auto lock snap off handle. The A300R comes complete with a 12 point snap off 45° blade. Made from solid plastic ABS, with a perfect weight distribution and an auto lock system meaning no matter the amount of pressure you apply, the blade will never return back. The NT CUTTER A300R also features it's own blade snap off tool. When a blade becomes dull, simply pull the snap off tool from the back, break the blade off to reveal a new sharp point. Ideal for vehicle wrapping, PPF, sign making, textile decoration, window tinting and digital printing applications. (When used for window tinting, replace the blade with OLFA AB-10S blade).
