## Long description

The Topex insulation knife for mineral wool with a 480 mm overall length and a 335 mm blade is a handheld cutting tool designed to make straight, controlled cuts in mineral wool insulation.

Key specifications
Overall length: 480 mm
Blade length: 335 mm
Tool type: handheld insulation knife for mineral wool
Intended material: mineral wool insulation
How to use
Place the mineral wool on a stable surface and measure the required dimensions. Hold the knife by its handle with a firm grip and align the blade along the marked cutting line. Make a steady, continuous stroke through the insulation using the full blade length where possible to ensure a straight edge. For thicker sections, use several controlled passes rather than excessive force to avoid jagged cuts. Replace or sharpen the blade as needed to maintain clean cutting performance.
Usage recommendations
Use appropriate personal protective equipment such as gloves, long sleeves and eye protection when cutting mineral wool. Work in a well-ventilated area and avoid inhaling dust; consider using a dust mask or respirator when generating loose fibres. Store the knife safely with the blade covered when not in use.
