The Secunorm Profi set standards in safety, robustness, and ergonomics over 40 years ago. Its successor takes it a step further. The newly designed aluminum handle provides significantly better handling and a more comfortable working experience. Just think of the new dual-sided slider, the pre-mounted ceramic blade, or the now incredibly easy blade change. When cutting, the proven automatic blade retraction protects you from cuts. You can feel "ergonomics" everywhere with the Secunorm 500, for example, through the new handle shape that fits perfectly in your hand, or through details like the pleasantly rounded knife end and the non-slip soft grip on the slider.
