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. Two state of the art curved toothed blades combine to offer the maximum amount of space for slidecutting with nothing to hold you back!
