Abstract: A folding knife according to one embodiment is provided and includes (a) a handle defining a blade cavity; (b) a blade having a first end which is pivotably coupled to the handle about a pivot; and (c) a biasing element disposed within the blade cavity of the handle. The blade has a detent formed therein on a lower edge thereof proximate to the pivot. The biasing element has a fixed first end and an opposing free second end which has a rounded ball member formed thereat. As the blade is closed towards the retracted position, the blade contacts and deflects the second end of the biasing element until the rounded ball member of the second end engages the blade detent, resulting in the blade being held in the retracted position.

Abstract: A portable blade sharpening system including a sharpening device having a main body and a clamping bar for securing a blade to be sharpened. Guide arms having openings are attached to the main body for receiving and guiding a support rod. The support rod is attached to a sharpening hone holder and is movable between a retracted and extended position. The sharpening hone holder has a channel for housing the support rod when it is in the retracted position. The clamping bar includes recessions for providing it with a lowprofile adjacent the clamped blade. The openings of the guide arms are substantially rectangular so that a consistent cutting angle is maintained.
