ABSTRACT:
A C-shaped framework includes an upright post and an outwardly projecting anvil on top of the post, the top surface of the anvil being slotted to receive the bight of a fish hook and thus orient the eye of the hook in a direction such that fly material can conveniently be attached to the hook. A tightening band includes a loop which extends over the bight of the hook and thus selectively secures a hook positioned in the anvil slot. The band is connected to a drawing stem translatably disposed in an outwardly projecting bearing block forming the bottom of the C-shaped framework. The lower end of the drawing stem projects downwardly below the bottom surface of the bearing block and has a transverse axle mounted thereon. A cam eccentrically journaled on the axle is rotated by a lever. In one direction of rotation of the cam, the drawing stem and attached band are free to be moved upwardly to release the hook; in the opposite direction of cam rotation, the cam bears against the bottom surface of the bearing block and by reaction translates the drawing stem in a downward direction so that the band loop tightly clamps the bight of the fish hook against the anvil. The effective length of the drawing stem can be adjusted for different hook sizes.
