OLFA's X Design series starts from a single question: how does a grip stay planted when you are pushing hard? The answer is a cross-sectional form that resists rotation in the hand without relying solely on friction. The Hyper AL Type applies that logic to a large cutter and adds a feature rarely found on cutting tools: a crank-shaped M-type claw at the body's rear.

That claw is the product's most distinctive engineering choice. Its bent, crank profile lets it slip into narrow gaps where a straight tool would catch. From there it can pry open cardboard, score sheet material, or pull staples. One less obvious use case is its compatibility with a screwdriver: if a screw has stripped in gypsum board or plywood and begun to spin freely, sliding the claw beneath the screw head while turning the driver adds just enough upward resistance to let the screw bite and back out. It is the kind of secondary function that takes a single-task tool and gives it a broader place on a workbench.
