Abstract: A clamp for holding a fish hook for sharpening, comprising a flat horizontal base (1), a first vertical plate (2) fixed to the base, and a second vertical plate (3) mounted against the first vertical plate by two bolts (7) with wing nuts (8). The base and vertical plates are preferably made of plastic. A horizontal groove (5) is cut in both vertical plates to receive the eye (9a) of a fish hook (9), allowing the shaft of the hook to fully contact the facing surfaces of the vertical plates. An optional second groove (6) in both plates receives the eyes of smaller hooks, so that both large and small hooks are automatically held at a convenient angle for sharpening. A sharpening stone (10) with a V-shaped channel (11) is preferably attached to the base with Velcro.
