The Secunorm 540 safety knife from martor combines automatic blade retraction (safety level 1) with a high-quality metal housing made of metal and glass-fibre-reinforced plastic that sits firmly in the hand even with frequent use. The 36 mm long polystyrene blade without snap-off segments cuts through thicker materials in one continuous cut instead of having to start several times – a clear advantage over shorter standard blades. Designed for intensive use with more than 1,000 cuts per day, the Secunorm 540 remains reliable and dimensionally stable even under continuous load in shift operation. This makes it the right choice for logistics managers and safety officers who need a robust, durable tool for high cutting frequencies in warehousing and shipping. Safety knives overview

This lets you judge whether it suits your application. If you have questions about the choice, we are happy to advise you personally.

The Secunorm 525 is the more compact version of the Secunorm 540: the same automatic blade retraction and one-sided slider, but with a shorter cutting depth of around 20 mm instead of 36 mm. If you mainly cut thinner materials and do not need a model with a long blade, the Secunorm 525 is a slimmer, equally safe alternative.
Alongside the Secunorm 540, CURT offers other safety knives with automatic blade retraction (safety level 1) for long blades: the US11 with a slider on both sides, the U002P with additional SoftGrip, the U010 made of continuous metal with a rear slider and the Secunorm 380 with up to 8 cm cutting depth for particularly thick materials. Depending on your grip preference and the blade length you need, you will find the right alternative here.
