This tool is basic yet widely applicable, relying entirely on the manual force of doctors or technicians for operation. The handle is ergonomically designed to be of appropriate thickness, with surfaces typically treated with anti-slip processes such as knurling or sandblasting, allowing users to apply force and grip firmly without causing hand fatigue even during prolonged use.

The shank is made of high-strength stainless steel, offering excellent rigidity, ensuring stability and preventing bending or deformation during torque transmission, thus accurately conveying hand force to the blade tip for effective screw operation. In single-tooth implant surgery, the manual torque technician's screwdriver, leveraging the doctor's rich tactile sense and experience, can precisely rotate the implant to the ideal position, laying a solid foundation for subsequent restoration work.
