OLFA's X Design series started from a single question: what shape lets a hand apply maximum force without slipping? The answer is the X-form grip, a rubber-covered body that channels grip pressure along the natural axis of the hand. The result is a cutter that stays put under load, which matters most when scoring thick cardboard or dense styrene board.

The Speed Blade bundled with this model adds a second layer of thinking. The blade steel is OLFA's standard special black alloy, ground at a sharper angle than a regular blade. The fluorine coating on the ground face reduces friction against the cut material, so the knife moves through stock with less effort. The effect is most obvious on long, continuous cuts where resistance normally builds up.

The rear claw is a small but considered addition for anyone who moves between cutting and unpacking work. It hooks under packing tape, pries open paint can lids, and spares the blade edge from tasks it was never meant for. The auto-lock mechanism holds the blade at any extension point with a single push, no twist required.
