The Basic safety knife from CURT is a safety level 1 knife with automatic blade retraction. The blade retracts as soon as the thumb releases the slider.
The impact-resistant plastic housing is reinforced with a sturdy sheet-metal rail that gives the blade a secure hold and keeps the knife dimensionally stable. The large handle sits securely even in large hands, a rubberised area on the back gives additional grip, and the large thumb slider runs smoothly. The Basic is therefore designed for frequent use of up to 1,000 cuts per day.
By turning the blade over, the Basic can be set up for right- and left-handed users. The blade is changed without tools directly at the workstation. Safety is additionally verified by a GS certificate.
The Basic is used above all where large quantities of packaging have to be opened every day – cutting off lids and flaps of cartons, cutting through PP and PET strapping and opening adhesive tape, film and bags. Its focus is on logistics, shipping and retail branches, where the price per knife counts. Safety knives overview
Which materials is this knife made for — and where does it reach its limits?
The 19 mm blade cuts through PP and PET strapping in one clean pass.
The Basic quickly opens adhesive tape and strapping on cartons, after which the blade retracts immediately.
The long blade cuts lids, flaps and window cuts in corrugated board in one pass.
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 you can see at a glance how the Basic safety knife 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 choosing, we are happy to help you personally.
Automatic blade retraction — the blade retracts by itself as soon as you release the handle, no need to push it back manually.
