THINKWORK All-Metal Retractable Utility Knife Box Cutter w/ Glass Breaker

【ALL METAL BODY UTILITY KNIFE】Say goodbye to plastic-handled knives that crack at the slightest strain. This heavy-duty utility knife is precision-machined from solid aluminum alloy—it won’t bend or break, whether it falls off a ladder or gets buried in a cluttered toolbox. Designed specifically for construction sites, warehouses, roofing projects, and drywall work.
【2-IN-1: CUTTER + GLASS BREAKER】One tool, two uses. The SK4 razor blade effortlessly cuts through cardboard, drywall, carpet, strapping, rope, twine, and leather. In an urgent, the hardened hammer head at the end of the handle can shatter car or house windows, helping you escape quickly.
【BLADE QUICK-CHANGE DESIGN】No more rummaging through your toolbox for a new blade. Simply press the release button to safely eject the dull blade, remove a new blade from the blade compartment, and insert it—the entire process takes less than 10 seconds. The built-in rear compartment holds six high-toughness SK4 spare blades (HRC 62). With sharp replacement blades always on hand, you can keep working without interruption.
【3 DEPTH ADJUSTMENT 】Select the blade extension length that best suits your needs. Push the locking button forward to securely lock the blade in any of the three positions. After use, retract the blade completely. Working on a ladder or scaffolding? Thread a safety lanyard through the rear eyelet and secure it to your tool belt to prevent the knife from accidentally falling. The ergonomic curved handle provides a comfortable and non-slip grip.
【THE GO‑TO TOOL FOR PROS】Whether you’re a contractor, electrician, mover, warehouse worker, or seasoned DIYer, this professional utility knife streamlines your workflow. It handles thousands of cuts without fatigue – opening boxes, cutting foam, trimming wallpaper, rubber, leather, and PVC, and more.
