Advantages

The fixed-blade design eliminates blade play and ensures consistent cutting depth and alignment. Compact 190 mm overall length makes the knife easy to handle in tight spaces while providing sufficient blade exposure for common installation tasks. The simple construction reduces maintenance and the risk of mechanical failure, and the robust handle gives secure grip during repetitive work. This model is suitable where a dependable, durable cutting tool is required without complex mechanisms.

Suitable for

• Scoring and trimming drywall paper and gypsum board
• Cutting cardboard and packaging materials
• Shaping and trimming insulation panels and foam
• General-purpose cutting during renovation and assembly work

Key specifications

• Overall length: 190 mm
• Blade type: fixed blade (non-retractable)
• Intended use: assembly and installer’s cutting tasks
• Typical materials: drywall paper, cardboard, insulation, foam and similar sheet materials
• Design: simple, robust handle for secure grip

How to use

Hold the knife with a firm grip and position the fixed blade at the start of the cut. For scoring, apply steady pressure along the cutting line and repeat as needed to penetrate the material without forcing the blade. For trimming or through-cuts, use controlled strokes and keep the material supported to avoid jagged edges. Replace the knife if the blade becomes dull or damaged; the fixed-blade design may require service or replacement of the entire unit depending on the model construction.

Usage recommendations

Use personal protective equipment such as cut-resistant gloves and eye protection when cutting. Keep fingers clear of the blade path and maintain a stable work surface. Store the knife in a secure location when not in use to prevent accidental contact.
