The BSC PREFERRED KN109 is a safety box cutter designed for repetitive cutting tasks in shipping, receiving, and warehousing environments. The thumb-activated, spring-back safety guard returns to the closed position automatically after each top cut, reducing the risk of accidental contact with the blade. A separate blade extension button allows for tray cuts without exposing the full blade. The KN109 also features a bladeless tape-splitting function that lets users open taped cartons without deploying the blade at all, eliminating a common source of hand injuries on the dock floor. Each unit stores up to 5 blades internally and ships with one SP-017 Single-Notch Safety Blade (KN216) included.
The KN109 is suited for general-purpose carton opening in distribution centers, stockrooms, and trade supply operations where workers handle high volumes of packaged goods daily. The ergonomic handle and ambidextrous design accommodate both right- and left-handed users without adjustment. This SKU is sold as a case of 12 individual cutters, making it appropriate for outfitting a crew or restocking a tool crib. Installation professionals, warehouse staff, and receiving teams who routinely break down HVAC, plumbing, or electrical supply shipments will find this a practical addition to their kit.
Designed for use with SP-017 Single-Notch Safety Blades (KN216). Compatible replacement blades should match the SP-017 single-notch specification to fit correctly in the blade carriage.
No installation is required. Before loading or replacing a blade, retract the guard fully and handle the blade only at the non-cutting edge or with a blade-change tool. Dispose of used blades in a puncture-resistant sharps container in compliance with applicable workplace safety regulations. Inspect the spring-back guard mechanism periodically to confirm it returns fully to the closed position after each cut.
