Knives for Sacks & Thick Materials

Description

Knives for sacks and thick materials are safety knives with a large cutting depth, designed for tasks where standard knives are no longer enough. They handle the opening of paper and plastic sacks, as well as the cutting of bulky, dense materials such as foam, polystyrene, rubber and paper rolls – without compromising operator safety.

In this subcategory you will find specialised MARTOR knives for warehouses, manufacturing facilities, construction and logistics. Every model is GS-certified and features automatic blade retraction, which returns the blade to the handle immediately after cutting.

How to Choose a Knife for Sacks or Thick Materials?

The choice depends on the type of task – whether you are opening sacks or cutting bulky materials – and on the cutting depth you need:

  • For opening sacks – SECUNORM 610 XDR. A universal bag opener with a 32 mm cutting depth, resistant to dust, liquids and sticky contents (eXtra Dirt Resistant). It opens sacks of any kind – from simple film to multi-ply kraft paper. Metal-detectable.
  • For foam, polystyrene and bulky materials – SECUNORM 540. A large cutting depth of up to 36 mm and a sturdy aluminium body for the toughest tasks.
  • For the thickest materials and 4-ply cardboard – SECUNORM 380. The world's first knife with automatic blade retraction and a blade almost 8 cm long, with an additional transport lock.
  • Safety knife and utility knife in one – SECUBASE 383. Adjustable depth in 7 positions (from 7 to 73 mm) and a choice between automatic retraction or locking the blade. Ideal for foam, polystyrene and multi-ply cardboard.

Why a Large Cutting Depth with Safety?

Deep cuts are traditionally made with fixed-blade utility knives, whose blade stays exposed and poses a serious risk of cuts. MARTOR safety knives for thick materials solve this problem – they offer a large cutting depth, but the blade retracts automatically as soon as it leaves the material. So you get the power of a large blade without the permanently exposed edge.
