DongCheng 18mm Heavy-Duty Snap-Off Knife (HD110118)
Have a question?
The DongCheng HD110118 18mm Heavy-Duty Snap-Off Knife is built for tough jobsite utility cutting, packaging breakdown, drywall scoring, carpet trimming, and rubber sheet slicing. Equipped with an extra-thick 0.5 x 18 x 100mm CK75 high-carbon alloy steel blade, it provides edge sharpness while resisting blade bending during forceful cutting passes.
When the point wears down, snapping off the scored segment instantly reveals a sharp new edge. The 170mm handle is molded from durable polypropylene (PP) plastic, providing an ergonomic, non-slip grip that fits comfortably in the palm during heavy dragging cuts. Built with a smooth slide-lock system to secure blade extension, it comes packaged in a protective plastic bag.
