This WALNUT lame is meant for blade holders, specifically the ones who were stubborn enough to dare not embrace the UFO or Arc lames! You know who you are! So, I took it as a personal challenge to go even smaller: maintaining our design philosophy of no knobs, beautiful aesthetics, no plastics, simple. You keep your thumb on the blade while scoring, intimate, but it's much safer than handling a bare blade. And when you're done, you tuck the blade inside for safe keeping.
