Replacement blades WEDO trapezoidal 19 mm for left-handed cutter, universal size

Set of WEDO replacement trapezoidal blades with 19 mm cutting width designed for left-handed cutters. These universal-size blades are made for precise straight cuts on paper, cardboard, film and similar thin materials and are suitable for compatible utility knives and cutters. The pack restores cutting performance and safety by allowing quick blade changes when the original blade becomes dull.

Advantages

The trapezoidal geometry provides a robust cutting edge and predictable cut behaviour while the 19 mm width balances control and coverage for straight trimming tasks. Blades are manufactured to consistent dimensions to ensure they fit left-handed cutters and other compatible safety knives. Replacing dull blades is fast and reduces the need to apply additional force, which improves control and lowers the risk of slips during cutting.

Suitable for

• Cutting paper and cardstock in office and craft projects
• Trimming film, laminates and thin plastics
• Workshop tasks requiring straight, repeatable cuts
• Left-handed users using compatible utility knives and cutters

Key specifications

• Blade shape: trapezoidal
• Cutting width: 19 mm
• Compatibility: universal size for compatible utility knives and left-handed cutters
• Material: high-carbon or stainless steel cutting edge (manufacturing grade for consistent sharpness)
• Intended materials: paper, cardboard, thin film, laminates

How to use

Ensure the cutter is designed for left-handed operation and is compatible with 19 mm trapezoidal replacement blades. Remove the spent blade following the cutter manufacturer’s instructions, taking care to avoid direct contact with the cutting edge. Install a new blade securely in the holder or mechanism so it is fully seated and locked before use. Test a short cut on scrap material to confirm correct blade alignment and secure mounting.

Recommendations

Replace blades as soon as cutting quality degrades or more force is required. Store spare blades in their original packaging or a dedicated container to prevent accidental cuts. Use protective gloves and cut on a stable cutting surface or mat to extend blade life and maintain safety.
