There is no need to use secondary tools to break and remove the snap-off blade. Simply line up the blade with the indicator line, release the lock and push over the built-in blade snapper and continue cutting with a fresh new sharp edge. For added convenience, the knife retains the blade once it's snapped with an integrated magnet. The knife is made from hard-wearing stainless steel for high-endurance and long life. Its pro-grade depth control with wheel lock allows for seamless, intuitive blade depth setting. It is fitted with a rugged, bi-material handle for increased grip and comfort. Ideal for repetitive cutting applications, such as in a workshop or at home.
