OLFA SAC-1 is easily the best and most used handle in the industry. The SAC-1 comes complete with a 6 point snap off SAB 30° blade. Made from high quality Stainless Steel, 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 OLFA SAC-1 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).
