Apply High Torque
The handle's three-sided geometry directly engages the structure of your hand, instead of relying on friction with your skin, so you can apply high force with less fatigue.
Spin Fasteners Quickly
Round sections at the front and back ends of the handle allow you to spin long, finely threaded fasteners quickly and continuously.
Durable, Nonslip Handle
The overmolded grip provides a nonslip surface that is permanently bonded to the handle and won't degrade or become sticky over time.

Materials and Construction
AISI 8650 Steel Blade
- Strong Ni-Cr-Mo alloy hardened to HRC 52–56
- Chrome-plated shaft finish for increased corrosion resistance
- Reinforced with calcium carbonate for dimensional stability
- Shore D 68 durometer
- Soft thermoplastic elastomer (TPE)
- Shore A 80 durometer
Insert Molded for Exceptional Strength
We use a molding process that forms the handle around the blade, rather than forcing the blade into a premade handle. The result is a straighter blade that can’t twist out.
