Based on the revolutionary weight-adjustable handle design, the new Pro-Balance introduces the new slotted Axel. Unlike the previous version “long screw” Axel, the new Pro-Balance featured a much more efficient process. You can easily adjust the knife into the most comfortable weight balance in just a few seconds. Satin surface treatment on the handle can prevent the knife from slipping off the users’ hands. The unique color coding system is improved to a detachable mechanism. Users may choose their favorite color by simply inserting various color rings into the component.
