## Long description

The Erko NMZS 50 Electrician's Knife with Guide Shoe is a professional-grade tool engineered for precision in electrical installation and cable preparation.

Advantages
The primary benefit of this electrician's knife is the inclusion of a specialized guide shoe, which significantly enhances safety and accuracy by controlling the depth of the cut.

When it may not be suitable
This knife is not intended for heavy-duty cutting tasks such as sawing through thick conduits, metal, or wood. It is specifically optimized for cable insulation and should not be used as a general-purpose utility knife for construction materials that could damage the precision edge of the blade.
Key specifications
Blade length: 50mm
Integrated guide shoe for depth control
Ergonomic handle design

How to use
To use the Erko NMZS 50, position the guide shoe against the cable insulation at the desired stripping point. Apply steady, controlled pressure to pierce the insulation, then draw the knife along the cable length. The guide shoe will maintain the blade at a consistent depth, preventing accidental contact with the copper or aluminum conductors inside. Always ensure the cable is stable before beginning the cut.
What to consider before purchase
Verify the blade length meets your specific cable stripping requirements
Ensure the tool is used only on compatible cable types
Consider the need for regular blade maintenance to ensure continued precision
Usage recommendations
Always cut away from your body and keep fingers clear of the blade path. Regularly inspect the blade for signs of dulling or damage to maintain safety and performance standards. Store the knife in a protective sheath when not in use to preserve the edge.
