The H-type blade format exists specifically for materials that push a standard large (L-type) blade to its limit. Flooring panels, gypsum board, and dense foam all require a thicker, wider cutting edge that resists the lateral flex responsible for inaccurate cuts and blade breakage. OLFA's H-type blade answers that with a 0.7mm thickness, compared to the 0.5mm of the common L-type, and a full 25mm width that keeps more of the blade in contact with the material.

The 151BG wraps that blade in a body sized for hands that find standard large knives cramped. At 178.5mm long and nearly 30mm deep, it distributes grip pressure across a larger surface area, reducing fatigue on extended cuts. The elastomer resin grip adds traction specifically in the conditions where grip loss is most likely: damp hands, latex gloves, or dusty job-site environments. The screw-lock, rather than a slider or auto-lock, holds the blade tip position without any play, which matters when the cutting force is high enough to shift a less secure mechanism.
