The BSC PREFERRED QB189 - B/C is a utility knife built for trades and general-purpose cutting tasks. It handles common jobsite work including opening packaging, scoring materials, trimming insulation, and cutting strapping.

At 0.18 pounds, it is lightweight enough for repeated use without hand fatigue.

The QB189 - B/C is suited for residential and light commercial jobsite use. It fits naturally into any toolkit where a compact, fixed or retractable blade knife is needed for cutting tasks such as trimming pipe insulation, slitting wire loom, scoring drywall, or breaking down material packaging. The small form factor makes it practical for confined spaces and overhead work. This is a single-unit item sold per each, with a minimum order quantity of 20 units, making it practical for stocking service vehicles or shop supply cabinets.
Designed as a general-purpose utility knife for use across HVAC, plumbing, electrical, and general construction trades as a standard jobsite cutting tool.
Utility knives should always be directed away from the body during use. Store with the blade retracted or capped when not in use. Keep blades sharp — a dull blade requires more force and increases the risk of slipping. This product contains chemicals known to the State of California to cause cancer and reproductive harm.
