Double-Edged Utility Knife Erdi YT-75220 — Erdi double blade replacement knife

Erdi YT-75220 is a double-edged utility knife designed for general cutting tasks. The compact handheld body houses a replaceable double-sided blade so each blade can be rotated or flipped to use a second cutting edge, extending service life between blade replacements. The knife is intended for controlled, repeatable cuts in materials such as cardboard, tape, packaging film and other light-duty workshop tasks where a reliable, easy-to-handle cutter is required.

Advantages

The double-edged blade design provides two usable cutting edges per blade, increasing efficiency and reducing the frequency of blade changes. The compact form factor allows comfortable one-handed operation and precise control during trimming and scoring. The replaceable blade mechanism simplifies maintenance and keeps the tool ready for continuous use. Materials and construction focus on practical durability suitable for packaging and light workshop environments.

Suitable for

• Cutting cardboard and corrugated boxes
• Opening and trimming packaging tape and film
• Light-duty workshop trimming and scoring
• Repeatable cuts where compact control is required

Key specifications

• Blade type: double-edged replaceable utility blade
• Handle style: compact handheld body for single-hand operation
• Intended use: light to general-purpose cutting tasks
• Typical materials: cardboard, tape, packaging film and similar materials
• Maintenance: blade replacement mechanism for continued use

How to use

Hold the compact handle in one hand and align the cutting edge with the material to be cut. Apply steady, even pressure and guide the knife along the cut line for a controlled result. When one edge becomes dull, rotate or flip the double-edged blade (or replace the blade) according to the manufacturer's blade-change procedure to restore cutting performance. Store the knife with the blade retracted or safely covered when not in use.

Usage recommendations

Use appropriate personal protective equipment such as cut-resistant gloves and eye protection when working with blades. Keep the knife away from children and ensure blades are securely fastened before use. For the best results on thicker or tougher materials, make several light passes rather than forcing a single deep cut.
