Everything about EVO is state-of-the-art. The steel is the finest cobalt/molybdenum alloy in the world. We are the only company to ever cryogenically temper this grade of steel. You could stop there and make a case for these as the best. The tension is controlled by a ball-bearing leaf-spring system that will feel like new for years and years. Metal to metal wear in the pivot is eliminated by our teflon pivot glides. The handle is our tribute to the original Hineta crane design, simply beautiful.
