OLFA's SKB-10 Four-Position Replacement Safety Blade (10 Pack) provides a straightforward way to maintain compatible OLFA safety knives without replacing the complete tool. Each blade can be indexed through four positions, allowing users to move to a fresh cutting edge when the active edge becomes worn. This design helps make better use of each blade while supporting the controlled cutting characteristics expected from a safety knife. The blade is intended for compatible OLFA models and is well suited to repetitive package-opening and material-handling applications. Common uses include cutting cardboard, plastic film, tape, shrink-wrap, and plastic strapping in warehouses, shipping departments, retail environments, construction settings, and other workplaces where replacement safety blades are routinely needed
