Cutter knife Secubase 383 – with automatic blade retraction that can be switched off

Cutting depth 73 mm | steel rail, plastic housing | cutting depth adjustment

The martor Secubase 383 is a cutter knife of safety level 0 with automatic blade retraction that can be switched off. The blade retracts as soon as the thumb releases the slider. For cuts with a fixed blade, such as sawing cuts, it can be locked in seven positions according to the manufacturer. The knife then works like a classic cutter knife.

The housing is made of glass-fibre-reinforced plastic with a steel rail, and the soft grip ensures a secure hold. The ergonomic design and the large thumb slider make operation easier. This makes the knife suitable for frequent use of up to 1,000 cuts per day.

After conversion, the knife is suitable for right- and left-handed users. The cutting depth is adjustable, you change the blade without tools, and the GS certificate confirms tested safety. At 78 g it is also light.

The Secubase 383 can be used universally, from cardboard, film and adhesive tape to strapping, but it is particularly suitable for polystyrene and foam: the fitted polystyrene blade cuts up to 73 mm deep. It is used in logistics, retail, production and the trades. You will find further models in the overview of safety knives.

Further features

Safety

Transport lock

Prevents the blade from extending by accident in a pocket or tool case.

Magnet for blade changes

Lets you change the blade without tools and without touching the sharp blade directly.

Without snap-off segments

Continuous blade without predetermined breaking points, no risk of a segment breaking off uncontrolled.

Handle & ergonomics

Ergonomic design

The handle shape is designed around the hand position when cutting and reduces fatigue with repeated use.

SoftGrip

Reduces fatigue over long shifts thanks to grippy, padded zones.

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.

Large slider

Generously sized, can be operated safely and over a large area, even with gloves.

Weight < 100 g

Noticeably lighter than all-metal knives without giving up stability. Comfortable with frequent, repeated use throughout the day. This model weighs 78 g.

Blade

Adjustable cutting depth

Can be limited to protect the material underneath, e.g. the contents of a carton, from damage.

Premium carbon steel

Refined alloy with even better edge retention, for particularly demanding continuous use.

Uncoated

Constant basic sharpness without coating wear, cost-efficient and proven. The most economical choice for standard applications.

High initial sharpness

Especially sharp from the first cut, ideal when maximum cutting performance is needed immediately.

Long edge life

Much longer service life until the next blade change than standard blades. Reduces change intervals and blade consumption in intensive use.

Special features

Tool-free blade change

Insert a new blade without tools, done in seconds.

Eyelet

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