Do It RK13C-DIB 9mm Snap-off Knife Auto Lock

Product Description

The DO IT RK13C-DIB is a 9mm snap-off utility knife built for trade and job-site use. It features an auto-lock slide mechanism that secures the blade position quickly without fumbling, keeping the edge stable during cuts. The knife ships with three blackened carbon steel blades described as sharper and more keen than standard snap blades. A stainless-steel track guides the blade with minimal lateral play, and the heavy-duty soft-grip handle reduces hand fatigue during extended use. A built-in blade snapper lets the user safely break off a dull segment to expose a fresh cutting point without needing a separate tool.

The RK13C-DIB is suited for cutting drywall, cardboard, insulation, housewrap, flooring underlayment, and similar sheet materials on residential and light commercial job sites. It is a practical everyday-carry cutter for HVAC installers, electricians, plumbers, and general contractors who need a reliable scoring and trim knife on hand. The compact 9mm blade width handles detail work and straight cuts alike.
