ABSTRACT:
A fly-tying vise has a vise portion for gripping a fly-tying hook supported by a vertical support post above a clamp portion for gripping the free edge of a tabletop. A jaw assembly of the vise portion has a pair of hook-clamping jaws opened and closed by a thumb screw. The jaw assembly cooperates with a spring-biased detent to allow rotation of the jaws without changing their closure setting through application of a combined axial and torsional pressure to the thumb screw. The clamp portion includes a sleeve slidably adjustable along the support post and a pair of clamping arms, one fixed to and the other slidable along the sleeve to adjust for different tabletop thicknesses. The slidable arm carries a thumb-screw-operated bearing disc which creates a bind between the slidable arm and sleeve to hold such arm in an adjusted position when the disc and fixed arm bear against opposed surfaces of a tabletop.
