Most large cutter knives share a common problem: as the blade extends further out, it begins to flex and wobble, reducing accuracy and increasing the risk of slipping. OLFA addressed this with the OL Type by engineering a specially shaped blade holder that keeps the blade stable even at long extension lengths. The result is a tool that can take on carpet cutting, a task that demands both reach and control.

The claw tip is a small but considered addition. Carpet edges tend to curl or shift during cutting, and the claw lets the user pin the edge in place without needing a free hand. The screw-lock mechanism, rather than a slider, holds the blade firmly all the way to the tip, which matters when the blade is under lateral pressure from dense material. The body combines ABS resin with stainless steel and carbon steel components, keeping weight down while maintaining rigidity where it counts.
