The Secunorm 500 stands out for its ergonomic design, which sits securely and without fatigue in the hand even during intensive continuous use with well over 1,000 cuts per day. At only 73 grams it is one of the lightest safety knives in its class and therefore remains comfortable to guide over full shifts. The thumb slider can be operated directly from both sides – right- and left-handed users can switch hands at any time without conversion, which saves time at changing workstations in logistics, retail or production. For safety officers and logistics managers who rely on low weight combined with high handling safety, the Secunorm 500 is therefore a well-thought-out choice for everyday professional work. More on safety levels and selection criteria: Overview of safety knives
The Secunorm 500 shows its strengths across a wide range of cutting tasks: corrugated board, adhesive tape and PVC film are cut through just as reliably as PP or PET strapping. The trapezoid blade also delivers clean cuts on rubber, non-woven fabrics and thick films, as well as on big bag cords and polystyrene.
Safely open cartons, cut off flaps and cut them up – even multi-wall corrugated board is cut through in a controlled way.
Rubber mats and elastic seals are cut off cleanly with the robust, sharp blade.
Tensioned PP and PET strapping is cut through safely and in a controlled way.
Not every safety knife is built the same – and you only notice it when it matters in everyday use. In the knife know-how section we show you at a glance how the Secunorm 500 performs in the most important respects: from the safety mechanism and grip quality to blade performance. This lets you judge whether it suits your application. If you have questions about the choice, we are happy to advise you personally.
Automatic blade retraction — the blade retracts by itself as soon as you release the handle, no need to push it back manually.
