The OLFA MT-1/WP was designed & developed on request from British decorators. It is the only cutter made specifically for cutting wallpaper, and it does that very task effortlessly. The specially designed Excel Black ultra sharp blade simply glides through without snagging or tearing the paper, even when its wet. The blade has been developed with a unique 65° angle, which was researched to be the ideal angle for cutting paper against a wall, and getting into corners. The cutter features a precise auto-lock mechanism that keeps the blade firmly in place when cutting, resulting in perfect cuts and invisible joins. Small ridges on the ABS plastic allow you to apply pressure with your index finger, without the fear of slipping. Fully furnished with a built-in blade snapper & pocket clip, this cutter is ideal for any wallpapering job. The stainless steel blade channel will remain rust-free forever.
