Secunorm 300 – light safety knife with automatic blade retraction

Automatic blade retraction | cutting depth 17 mm | glass-fibre-reinforced

The Secunorm 300 is a light safety knife with automatic blade retraction (safety level 1). As soon as the slider is released or the blade leaves the material being cut, it retracts into the housing on its own.

With a cutting depth of 17 mm, it covers the usual cutting work in logistics and production. The housing is made of glass-fibre-reinforced plastic, and the trapezoid blade 65232 is fitted.

Applications & cutting materials

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

For everyday cuts in the warehouse and shipping

Stretch film — Safety knife martor Secunorm 300 with trapezoid blade 65232 im Einsatz

Stretch film

You cut open the film over the carton at the edge; the blade then retracts into the housing on its own.

Adhesive tape — Safety knife martor Secunorm 300 with trapezoid blade 65232 im Einsatz

Adhesive tape

You open the adhesive tape in the lid seam with a short pull; the housing made of glass-fibre-reinforced plastic sits lightly in the hand even with many cartons a day.

Strapping — Safety knife martor Secunorm 300 with trapezoid blade 65232 im Einsatz

Strapping

You cut the strapping on the film-wrapped pallet safely; after the cut, the blade disappears into the housing immediately.

Further features
Knife type: safety knife
Safety knives are designed for continuous professional use — usually with an automatic or manual blade guard that prevents cuts when the knife is not in use. The standard choice in logistics, retail and production.
Ergonomics: ergonomic design
Ergonomic design — the handle shape is designed around the hand position when cutting and reduces fatigue with repeated use.
Ergonomics: tool-free blade change
Tool-free blade change — insert a new blade without tools, done in seconds.
Ergonomics: thumb slider
Thumb slider — the blade is pushed forward with the thumb in the classic way.
Ergonomics: left- and right-handed
Left- and right-handed — can be used with either hand, with or without conversion depending on the model, equally suitable for left- and right-handed users.
Ergonomics: large slider
Large slider — generously sized, can be operated safely and over a large area, even with gloves.
Ergonomics: smooth-running slider
Smooth-running slider — operates with little effort, noticeably more comfortable with frequent use.
Weight: < 100 g
< 100 g — noticeably lighter than all-metal knives without compromising on stability. Comfortable with frequent, repeated use throughout the day. This model weighs 52 g.
Material: premium carbon steel
Premium carbon steel — refined alloy with even better edge retention, for particularly demanding continuous use.
Coating: uncoated
Uncoated — constant basic sharpness without coating wear, cost-efficient and proven. The most economical choice for standard applications.
Sharpness: normal initial sharpness
Normal initial sharpness — solid basic sharpness from the first cut, entirely sufficient for everyday use.
Sharpness: long edge life
Long edge life — much longer service life until the next blade change than standard blades. Reduces change intervals and blade consumption in intensive use.
Blade safety: without snap-off segments
Without snap-off segments — continuous blade without predetermined breaking points, no risk of a segment breaking off uncontrolled.
