Rotary replacement blade features a remarkably sharp edge for clean, consistent cuts. Titanium-bonded blades are three times stronger than stainless steel to provide a blade that stays sharp longer. EZ change blade technology allows one-touch blade removal and simple snap-on of a replacement blade. Corrosion-resistant blade cuts up to 10 sheets of paper at a time. Replacement blade is designed for use with Westcott TrimAir Rotary Paper Trimmers (sold separately).
