The Wolfcraft Mineral Wool Knife with a 250 mm blade is a handheld cutting tool designed for working with mineral wool and other fibrous insulation materials. Its long straight blade allows precise trimming and shaping of insulation panels and rolls on construction and renovation sites. The tool is intended to support installers and DIY users by improving cutting accuracy and reducing material waste when fitting insulation around fixtures, walls, and pipes.

Advantages

The knife provides a clean, controlled cut through mineral wool thanks to its 250 mm blade length, enabling longer straight cuts without repositioning. An ergonomically designed handle supports comfortable grip and stable handling for repetitive cutting tasks. The robust blade and simple construction make the tool easy to maintain and suitable for frequent on-site use, while its compact handheld form factor facilitates transport and storage.

• On-site insulation fitting during construction and renovation
• DIY home insulation projects requiring precise straight cuts

Key specifications

• Blade length: 250 mm for extended cutting reach

• Handle: ergonomic design for improved grip and control
• Typical use environment: construction sites, renovation projects, and home DIY

How to use

Position the mineral wool on a stable surface and measure the required cut line. Hold the knife with a firm, comfortable grip and align the 250 mm blade along the marked line. Apply steady pressure and draw the blade through the insulation in a single, continuous motion where possible to obtain a straight edge. For thicker sections, make several shallow passes rather than forcing a single deep cut. After cutting, inspect the edge and trim any irregularities for a precise fit.

Usage recommendations

Use protective gloves and a dust mask when cutting mineral wool to reduce skin irritation and inhalation of fibers. Store the knife in a dry place and keep the blade covered or retracted if applicable to avoid accidental contact. Replace the blade if it becomes dull to maintain cutting quality and reduce tearing of insulation material.
