Pack of 50 trapezoid replacement blades by Irwin, model 10505824, designed for general-purpose utility and box cutter knives. These thin trapezoid blades provide multiple cutting edges for precise slicing of cardboard, plastic, carpet and other materials. Supplied as bulk replacement blades for workshops, construction, packaging and craft applications, the set ensures quick swaps to maintain sharp performance during repetitive cutting tasks.

Advantages

The Irwin trapezoid blades are made to offer consistent edge geometry for reliable, straight cuts and reduced tearing on common materials. Their thin profile enables accurate scoring and controlled slicing while the trapezoid shape provides several usable edges per blade, extending service life compared with single-edge blades. Packed in a set of 50, these replacement blades reduce downtime by allowing frequent blade changes and are suitable for high-volume environments where quick, safe swaps are required.

• Cutting and trimming cardboard and corrugated board

How to use

Install the blade according to your utility knife manufacturer's instructions, ensuring the knife is locked before cutting. Use one hand to hold the knife and the other to steady the material, applying even pressure and cutting away from your body. Rotate or replace blades when the cutting performance diminishes to maintain safety and accuracy. Dispose of used blades in a designated sharps container or wrap them securely before discarding according to local regulations.

Usage recommendations

For best results, use these trapezoid blades with utility knives that securely clamp the short, trapezoid profile. Replace blades frequently when cutting abrasive materials such as carpet backing or abrasive tape to preserve cut quality. Store the pack in a dry place to prevent corrosion and handle blades with protective gloves when changing to reduce risk of cuts.
