Abstract: A knife sharpening device is provided having a knife sharpening assembly with first and second grinding wheels. A robotic arm is actuable to grip and draw a knife to be sharpened along a sharpening pathway running between the to grinding wheels. A digital camera may be employed to capture digital images of the knife to be sharpened which are communicated to a computer running software to compare the digital image to a database of knife images and adjust the speed of the grinding wheels to predetermined levels of a knife image matching with the digital image.

Abstract: An elongated handle has a pointed fish hook rotatably affixed to one end of the handle, the hook having two operating dispositions, a first disposition wherein the hook is open for gaffing purposes and a second disposition wherein the hook folded back against the handle to block the hook point for safety. A mechanism releasably secures the hook at either disposition. A button actuated mechanism releases the hook from either disposition so that the hook can be moved from one operating disposition to the other. Preferably the gaff further includes a bias for urging the hook toward its open, gaffing disposition.
