The steels used in our blades are specially selected for their superior edge qualities.Most all of these steels require preventive care to inhibit rust, especially in humid or marine environments. An occasional application of a quality metal sealer (ask your dealer) is all that is needed. If rust spotting does occur, a fine grade semi-chrome polish is recommend-ed. Occasionally carry-clip screws may become loose. Application of a releasable thread-lock to the threads prior to tightening (follow manufacturer's instructions) is recommended.
