The BSC PREFERRED KN129 is a fully featured auto-loading utility knife designed for fast, tool-free blade changes that reduce the risk of injury during blade handling. The handle is constructed from zinc die-cast metal with a powder-coated finish and wrapped in a thermoplastic rubber grip for a secure, comfortable hold during extended use. A built-in 5-blade storage compartment keeps spare blades accessible without requiring a separate pouch or box. Each knife ships with 5 SB-92 Standard Utility Blades (KN210 equivalent). This case quantity item is sold 10 units per case, making it practical for stocking jobsite toolboxes or maintenance supply rooms.
The KN129 suits a wide range of trade and facilities applications including HVAC installation, electrical rough-in, plumbing rough-in, packaging, and general maintenance where a reliable box cutter is a daily-use tool. The auto-loading mechanism eliminates the need to manually seat the blade, reducing downtime during high-frequency cutting tasks. At 5.5 pounds per case and compact package dimensions, this case packs and stores efficiently in supply trucks or warehouse shelving.
The KN129 accepts SB-92 Standard Utility Blades (KN210) and is listed as equivalent to part number H-1470. Designed as a direct replacement for standard utility knife cutters in trade, maintenance, and packaging applications.
No installation required. To change blades, engage the auto-load mechanism per the manufacturer instructions without using additional tools. Dispose of used blades in a puncture-resistant sharps container in accordance with local safety regulations. Store unused blades in the onboard compartment with the blade retracted when the knife is not in use.
