OLFA 25 mm H-1 Extra Heavy-Duty Utility Knife

The OLFA 25 mm H-1 Utility Knife is built for heavy-duty cutting and tough materials. It comes with a sturdy ABS handle and an anti-slip rubber inset for secure grip and comfort — even if your hands are wet or you’re working in humid conditions. The stainless-steel blade channel gives strong support and prevents flex while cutting. It is preloaded with a heavy-duty 25 mm snap-off blade. Each blade has multiple segments that you can snap off to reveal a fresh, sharp cutting edge without the need for sharpening. Changing blades is simple and tool-free thanks to the ratchet-lock mechanism.

This knife is ideal for cutting thick or layered materials like carpet, vinyl, heavy fabrics, cardboard, leather, canvas, vinyl sheeting, insulation, plastic sheeting and more. It is a reliable choice for sewing rooms, upholstery work, bag making, leatherwork, flooring, home renovation tasks or any project that demands strong cutting power and precision.
