Ultra Sharp for Thick Materials
The OLFA 25mm XH‑AL Fiberglass‑Reinforced Auto‑Lock Utility Knife is an extra heavy‑duty utility knife built for cutting tough materials in construction, roofing, and industrial use. The fiberglass‑reinforced body and oversized anti‑slip handle provide strength, control, and comfort.
Preloaded with a 25mm Ultra‑Sharp Black Blade that is thicker, stronger, and up to 25% sharper than standard blades, it delivers powerful, precise cuts. A stainless‑steel blade channel adds stability, while the auto‑lock and tool‑free blade change keep work fast and efficient.
