The OLFA 25mm H-1 Classic Extra Heavy-Duty Utility Knife with Rubber Inset is the choice for high-leverage cutting tasks. The durable ABS plastic handle and stainless-steel blade support create a robust knife ready for the toughest job sites.

Gain more leverage in damp or humid conditions with the rubber grip insert. This anti-slip addition adds stability and comfort. Adjust the blade to unlimited positions with the ratchet-dial locking system. Loosen the dial to set the blade depth, then tighten for performance cutting.

Never worry about extra tools when you need a new blade. Snap one of the seven segments of the preloaded Ultra-Sharp Black Snap Blade to reveal a new edge. OLFA Black Blades are dual honed to be 25% sharper than standard silver blades. When you need a full blade change, loosen the dial and the used blade. Insert a replacement blade, tighten, and return to cutting.

Fits all OLFA 25mm blades including HB Extra Heavy-Duty Silver Snap Blades, HH Hook Snap Blades, and HSW Saw Blade.

Cuts cardboard/corrugated, carpet, cement board, drywall, flexible plastics, gaskets, house wrap, landscape fabrics, linoleum, plastic sheeting, plastic straps, shingles, shrink wrap, tape, twine/rope, and more.
