Cutter knives are among the most common cause of hand injuries on production lines. Choosing the right series not only removes the source of risk, it also has to keep the workflow from slowing down. We compare the three main Martor safety knife series on exactly these two criteria.
Three series, three protection concepts
SECUMAX – Hidden cutting edge
The cutting edge is only exposed while cutting. During transport the blade is invisible, so accidental contact with a gloved hand is impossible. This series is preferred where cutting is occasional: warehouses, shipping operations and field maintenance.
SECUNORM – Semi-automatic retraction
The blade retracts completely as soon as the material is released. A separate trigger mechanism means the edge opens only with a deliberate pull movement of the material. This keeps productivity high on logistics and packaging lines where single-use boxes are opened constantly.
SECUPRO – Fully automatic retraction
The blade returns automatically the moment cutting is complete, without any additional movement by the user. This delivers the highest level of safety on lines that run continuously from start to finish.
The MDP series: for food and pharmaceutical production
Standard knives cannot be used in food and pharmaceutical production because of the risk of metal fragments. The MDP series is manufactured with plastic components that are detectable in metal detectors. The product itself does not trigger the detector, so no additional sieving step is required on the line.
A practical selection checklist
| Question | Recommendation |
|---|---|
| Is cutting frequent? | SECUPRO or SECUNORM |
| Is a visible blade a risk? | SECUMAX |
| Is a metal detector in place? | MDP series |
| Is the tool carried around constantly? | SECUMAX with belt bag accessories |
Implementation on site
For the best result, plan user training together with the product itself. The right knife combined with the right training measurably reduces the risk of incidents. Contact us for sample tests and on-site demonstrations.
