OLFA's Semi-Automatic Self-Retracting Safety Knife with Tape Splitter combines a controlled utility blade with features intended for efficient package opening and material handling. The semi-automatic retraction mechanism requires the user to release pressure for the blade to retract, helping limit the amount of exposed blade during cutting. Its integrated tape splitter provides a dedicated way to cut packaging tape, while the replaceable SKB-2 dual-edge safety blade helps support continued use of the tool. Designed for professional workplace applications, the SK-9 can handle common packaging materials such as corrugated cardboard, plastic film, tape, strapping, and shrink-wrap. The result is a versatile safety knife that supports repetitive cutting work while keeping key functions in a compact, purpose-built design
