SURPRISINGLY LIGHT. CONVINCINGLY GOOD. WITH ROUNDED-TIP TRAPEZOID BLADE. The SECUNORM 300 is the SECUNORM 500’s “little brother” and a further development of the SECUNORM PROFI LIGHT. It retains a pleasant lightness as well as the proven automatic blade retraction. You’ll discover much more in the optimised SECUNORM 300 all-rounder. For example, the especially ergonomic design, an increased Cutting depth, the new soft grip, and extremely user-friendly blade changing.
