DIYSELF 30 Pack 18mm Retractable Utility Knife Red

Pack of thirty 18 mm snap-off knives

This thirty-count box supplies a disposable retractable utility knife for every workstation. The red plastic handles are sized for a comfortable grip during repetitive cutting tasks. Offices, warehouses and home workshops can keep a spare in each drawer without worrying about sharpening. The pack is aimed at teams that value convenience over long-term tool ownership.

18 mm blade width limits material thickness

The 18 millimetre snap-off blade handles thicker paper, tape, cardboard, balsa, bass wood, foam board and mat board in a single pass. Thinner blades would require multiple scores on the same stock, slowing throughput. The wider edge also resists flex when cutting dense packaging materials such as courier boxes. Users cutting very thick timber or metal sheet should select a different tool class.

Retractable lock and snap segments simplify use

A sliding lock tab secures the blade at the chosen depth to prevent accidental retraction during heavy cuts. When the tip dulls, the scored segment snaps off to reveal a fresh edge without tools. The plastic body offers no blade storage, so used segments must be collected separately. First-time users sometimes extend too many segments, reducing rigidity and causing the blade to bend.
