The Stanley Snap Knife features a hard-wearing stainless steel construction for high-endurance and long life. Its pro-grade depth control with wheel lock allows for seamless, intuitive blade depth setting. The knife is designed for repetitive cutting applications and comes with a rugged, bi-material handle for increased grip and comfort. For added convenience, the snap-off blade can be easily replaced by lining up the blade with the indicator line, releasing the lock, and pushing over the built-in blade snapper. The knife retains the blade once it's snapped with an integrated magnet, allowing you to continue cutting with a fresh new edge.
