ABSTRACT:
A sacrificial anode element is connected to a knife blade to protect against galvanic corrosion. The knife also has non-metallic components that electrically insulate the metallic components of the knife from one another to further inhibit galvanic corrosion. The knife may be readily disassembled without tools. This feature enables a user to clean or dry the internal portions as well as to customize the knife by replacing its components with similar components of different materials, shapes and other useful properties. For example, a user may choose between a blade made of a metal that is exceedingly resistant to corrosion but dulls after an average period of use and a blade that is of average corrosion resistance but holds an edge exceedingly well. Other replaceable components may be selected from a group of like components of different colors. The different colors may indicate the type of metal of which the blade is made or other features of the customized knife configuration that would not be readily apparent to a user. The knife may be used in conjunction with a sheath made of a non-metallic material. The handle and sheath include features that promote the drainage of water to further inhibit corrosion.
