Abstract: A fishhook remover includes a tubular housing for retaining a cylindrical plunger biased toward the bottom of the fishhook remover by a compression spring bearing against the plunger in a handle end, capped by a knob. A T-shaped handled mounted on the plunger allows the fisherman to reciprocate the plunger within the tubular housing. A grabber hook extending from the working end of the plunger is used to grab the embedded fishhook by the shank. Pulling the handle toward the knob at the top of the device causes the fishhook to become aligned with fishhook aligning means consisting of a downwardly extending flange portion of the tubular housing and into a V-shaped notch in the flange portion. Further, a pair of opposed slots in the lower portion of the tubular housing allow the curved shank portion of the hook to slide through the slots as the fishhook is drawn into the lower portion of the housing and thereby the fishhook is withdrawn from the fish along the same path it took when it entered the fish.
