OLFA Cutter Blade – PB-800

Utility knives may use fixed, folding, or retractable or replaceable blades, and come in a wide variety of lengths and styles suited to the particular set of tasks they are designed to perform. Thus, an outdoors utility knife suited for camping or hunting might use a broad 75 to 130 millimetres (3–5 in) fixed blade, while a utility knife designed for the construction industry might feature a replaceable utility or razor blade for cutting packaging, cutting shingles, marking cut lines, or scraping paint.

Another utility knife often used for cutting open boxes consists of a simple sleeve around a rectangular handle into which single-edge utility blades can be inserted. The sleeve slides up and down on the handle, holding the blade in place during use and covering the blade when not in use. The blade holder may either retract or fold into the handle, much like a folding-blade pocketknife. The blade holder is designed to expose just enough edge to cut through one layer of corrugated fibreboard, to minimize chances of damaging contents of cardboard boxes.

WARNING

OLFA blades are extremely sharp. Handle with care. Wear safety goggles. Always be alert and attentive when using a cutter or knife. Take the time to fully learn the correct use and limitations of any cutter. Never assume that you know how to properly use a knife. Store knives and blades in a safe place. Keep out of reach of children !
