The 230B belongs to OLFA's X Design Hyper Series, a line built around the idea that a cutter knife's body should be as engineered as the blade it carries. The multi-layer construction starts with a double injection-molded rubber grip shaped specifically to channel hand pressure without slipping, then moves inward to an aluminum die-cast body finished in baked gunmetal coating, and ends at a stainless steel blade holder that has been through full-surface hardening and chrome plating for both strength and wear resistance.

The screw-lock mechanism gets particular attention here. Rather than a separately assembled head and shaft, the metal screw is manufactured in one piece through integrated cold heading, which produces a component with superior joint strength and fatigue resistance. A shot-blasted matte finish and nickel plating are applied afterward.

The included Special Black Blade is ground at a sharper angle than OLFA's standard blades and receives a two-stage grind that reduces chipping at acute angles. The result is a cutter that can hold a finer edge through more demanding cuts.
