Safety Cutter Martor Secunorm 175 — auto-retracting blade safety knife, single-edge, model 175

The Martor Secunorm 175 is an auto-retracting blade safety cutter with a single-edge design intended for controlled cutting of cardboard, film, tape and other common packaging materials. The tool features an automatic blade retraction mechanism that reduces exposure after each cut, supporting safer handling in environments such as warehouses, shipping stations and retail packing areas.

Advantages

The Secunorm 175 combines a simple single-edge blade with an automatic retraction system to reduce the risk of accidental contact with the cutting edge. Its compact shape and straightforward operation allow for fast, repeatable cuts while keeping user hands away from the blade when not actively cutting. The construction is geared toward routine packaging tasks where speed and protection are both required.

Suitable for

• Cutting cardboard boxes and corrugated board
• Opening plastic film and shrink wrap
• Breaking tape seals and removing packing straps
• General packing and unpacking tasks in warehouses, retail and shipping

When it may not be suitable

The single-edge blade and compact profile make this cutter well suited for light-to-medium packaging tasks but limit its effectiveness on very thick or reinforced materials. For precision work requiring very fine trimming or for industrial cutting of heavy materials, a specialist knife or heavier-duty cutter would be more appropriate. The automatic retraction mechanism is optimized for safety in standard use; intentional prolonged blade exposure is not supported.

Key specifications

• Blade type: single-edge blade
• Safety feature: automatic blade retraction after each cut
• Primary materials to cut: cardboard, film, adhesive tape, packaging materials
• Typical use environments: warehouse, shipping, retail packing stations

How to use

Hold the cutter with a firm grip and place the blade against the material to be cut. Apply steady forward pressure to perform the cut; the blade will retract automatically when pressure is released. Replace the blade according to the manufacturer’s instructions when signs of wear or reduced cutting performance appear. Inspect the cutter regularly for damage and ensure the retraction mechanism operates smoothly before each use.

What to consider before purchase

• Frequency of use and typical materials to be cut
• Need for automatic blade retraction for added safety
• Compatibility of single-edge blade design with cutting tasks
• Maintenance requirements such as blade replacement and cleaning

Usage recommendations

Use the Martor Secunorm 175 for routine packing and unpacking where quick, safe cuts are needed. Keep the cutter clean and replace blades when dull to maintain safe, efficient operation. Store the tool with the blade retracted and out of reach of unauthorized users.
