The part where everything is connected. Triangular shaped shaft for maximum grip and torque. Soft rubber handle on top. About 2 meters long to fit most vans, trailers, pick-up trucks, etc. Prepared for tool-free mounting of blades, indicator, and other cool stuff coming up later.
The maximum center load is 40 kg to avoid damage. Center load 50 kg or more may deform the shaft/handle permanently. 40kg is a lot of pressure. If you keep on breaking them, you should consider changing your career (bodyguard, bouncer, middle-school teacher, etc.)
