OLFA's 17-1/2 mm Dual-Edge Safety Utility Blades (10 Pack) provide a practical replacement option for users of the OLFA UTC-1 Utility Knife, SK-4 Semi-Automatic Self-Retracting Safety Knife, and SK-9 Semi-Automatic Self-Retracting Safety Knife with Tape Splitter. Each blade features two cutting edges, allowing the blade to be reversed for additional use while maintaining a sharp working edge. Measuring 17.5 mm wide and approximately 0.6 mm thick, the carbon tool steel construction combines rigidity with edge retention for repeated cutting tasks. These replacement blades are particularly useful in shipping, packaging, warehouse, manufacturing, and material-handling environments where cardboard, plastic film, strapping, tape, and similar materials are routinely cut.
