The DongCheng HD110502 10-Piece Hook Utility Knife Blade Set is designed for professional carpet installers, roofers, packaging workers, and flooring technicians. Featuring a hooked profile, these blades allow controlled slicing and pulling through heavy sheet materials without damaging or penetrating the subfloor or underlying surfaces.

Forged from Japanese-grade SK5 high-carbon alloy steel, each blade measures 0.6 x 19 x 49mm, delivering edge sharpness, wear resistance, and structural strength under heavy pulling force. Universally compatible with standard fixed and retractable utility knife handles, this 10-piece set is packed in a protective dispenser plastic box for safe, organized workshop and jobsite storage.
