The 9mm blade is forged from premium 9mm SK or #60 Carbon Steel (0.4mm thickness), offering superior sharpness and durability. It slices through paper, leather, and plastic with precision, ensuring clean cuts even after repeated use.

The lightweight ABS/PS/PP handle (9.1×1.8cm, only 5.2g) is designed for comfortable grip and easy portability. Its compact profile fits easily in pencil cases, pockets, or desk drawers, making it ideal for school and office use.

The advanced retractable mechanism, paired with a safety lock, allows for easy deployment and secure storage, minimizing injury risks. The blade fully retracts into the housing when not in use, ensuring safety in school and office environments.

Ideal for hobbyists and crafters to cut paper, leather, and plastic with precise control. The sharp 9mm blade and safe retractable design offer accuracy and peace of mind during creative tasks.

A practical desk tool for opening mail, cutting paper, and handling light office materials. Its compact profile fits easily into pencil cases or desk drawers without taking up space.

A safe and reliable tool for students working on art projects, paper crafts, and classroom tasks. Its lightweight design is easy to handle while the retractable blade ensures secure operation.
The snap-off blade system makes it easy to get a fresh edge in seconds. Here's the sequence.
Slide the blade fully back into the housing before releasing the lock.
Disengage the safety lock mechanism to access the blade segments.
Snap off the dulled segment along its scored line, away from your hand.
Slide the blade forward to expose a new sharp edge and re-lock the mechanism securely.
Wrap the snapped-off tip and dispose of it in a puncture-resistant container.
Matching the tool to the material avoids both wasted cuts and wasted money on the wrong knife.
