Safety knife martor Secunorm 175 – ergonomic, light and safe

automatic blade retraction | wide blade opening | outstanding ergonomics

The martor Secunorm 175 safety knife combines automatic blade retraction (safety level 1) with a wide, dirt-tolerant blade opening and a robust GRP handle. The outstanding ergonomics are particularly noticeable in intensive continuous use: the knife sits lightly and securely in the hand, can be operated from both sides by right- and left-handed users and weighs only 31 grams. The rectangular blade, ground on both sides, with a cutting depth of 10 mm achieves a very long edge life thanks to being usable four times – the blade change is tool-free and magnet-assisted. As a model of the martor brand, one of the best-known names in the field of safety knives, the Secunorm 175 is particularly widespread in retail and logistics, where many cartons, adhesive tape and strapping have to be cut every day. A proven, field-tested choice for safety officers and logistics managers. Safety knives overview

Applications & cutting materials

Which materials is this knife made for — and where does it reach its limits?

Ideal for cardboard, film and strapping

Corrugated board & cardboard — Safety knife martor Secunorm 175 im Einsatz

Corrugated board & cardboard

Opening, cutting off flaps of and breaking down cartons is one of the most frequent tasks in goods receiving. Single- to triple-wall corrugated board can be cut through in a controlled manner without damaging the contents.

Stretch & shrink film — Safety knife martor Secunorm 175 im Einsatz

Stretch & shrink film

Palletised goods are secured with stretch film. The multi-layer film is cut open quickly and in a controlled manner when unpacking.

Handle & ergonomics

Blade

Premium carbon steel
Refined alloy with even better edge retention, for particularly demanding continuous use.
High initial sharpness

Eyelet
For attaching to a belt, carabiner or lanyard so the knife stays within easy reach.
