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 low-profile adjacent the clamped blade. The openings of the guide arms are substantially rectangular so that a consistent cutting angle is maintained.
