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: 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.

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 68 g.

Material: carbon steel

Carbon steel — higher sharpness and longer edge retention than stainless steel. Ideal for dry environments with a high cutting frequency.

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: normal edge life

Normal edge life — usual service life until the blade is changed, in line with the market standard for this type of blade.

Blade safety: without snap-off segments

Without snap-off segments — continuous blade without predetermined breaking points, no risk of a segment breaking off uncontrolled.

Blade change – how it works

1 Pull the black blade lock on the handle body backwards and hold it
2 Slide the blade out to the side
3 Insert the new blade and release the black slider
4 Check that the slider and blade have latched — it must not be possible to slide the blade out to the side
5 Dispose of dull blades in a collection box

Frequently asked questions

The most frequently asked questions about the Tortoris US40 — from blade compatibility to the safety level and the right area of application.

Which safety level does the Tortoris US40 have?

The Tortoris US40 is a level 3 safety knife. This means: the blade lies permanently concealed behind the protective hook and never emerges exposed — neither when cutting nor when slipping or when being taken out of a pocket. Level 3 is the highest safety class in the industry-standard classification system for safety knives.

Which replacement blades fit the Tortoris US40?

Only the K005 protective hook blade fits the US40. The blade mount is proprietary — blades from other manufacturers are not compatible. The K005 is made of carbon steel, overmoulded with plastic and usable twice. It can be reordered directly in the CURT shop.

Is the Tortoris US40 suitable for left-handed users?

Yes. The Tortoris US40 is directly suitable for left- and right-handed users — no conversion, no special version required. The symmetrical design of the BoxCutter allows use in both directions without restrictions.

What is the Tortoris US40 best suited for?

The US40 is particularly suited to logistics, goods receiving and retail with occasional use of up to approx. 200 cuts a day. Strengths: PP strapping, adhesive tape, corrugated board and stretch film. The limited blade edge life makes it less suitable for intensive continuous use.
