Locking: Ratchet-lock wheel
Blade Channel: Stainless steel

How to Adjust Blade Depth
Slide the ratchet-lock wheel to extend the 9mm blade in precise increments; the mechanism locks it securely in place. To retract fully, slide the wheel past the end of the track — the ratchet releases and the blade seats safely inside the handle.

Precise and comfortable
The ratchet lock holds the blade exactly where I set it — no wobble, no slipping. The stainless channel feels substantial and the tool-free blade change is a breeze. Perfect for hobby work.

Great little knife
Lightweight but well-built. The blade depth control is precise, which matters for scoring plastic and trimming model parts. Only wish it came with more blades.

A workhorse in my studio
I teach art and craft classes and I recommend this knife to all my adult students. The ratchet lock gives students confidence because the blade genuinely doesn't shift mid-cut, and the stainless channel resists the glue and paint splatter that destroys cheaper knives. The tool-free blade change means no lost screws or stuck blades. It's been dropped on concrete more than once and keeps working.

Good but took getting used to
The ratchet mechanism felt stiff at first and took a few days to break in. Now it operates smoothly and I appreciate the secure lock. Build quality is good for the price, but the initial stiffness earned it three stars.

Excellent for model building
Bought this for scale model work. The fine 9mm blade and precise depth control let me scribe panel lines and trim parts cleanly. Handle is comfortable for long sessions too.
