Hardware, Power and Hand Tools Design Bamboo Joint Screwdriver by Wenkai Xue Plus+ is a modular screwdriver designed for compact storage and quick tool selection. Each section carries a different tool bit. Sections can be added or removed to change the total length, so Plus+ adapts to different working spaces and stays easy to carry. The tool holder lets bits be inserted and removed quickly, and the grip is comfortable to hold. A clear symbol on each bit makes the correct head simple to recognize. The body is shaped by rubber injection molding. The modular units reduce storage space and resource waste.
