Abstract: Disclosed is a uni-knot tying device. The device includes a stator, a hollow cylindrical rotor which is rotatably mounted on the stator, and a rotating drive operatively coupled to the rotor. The rotor has a proximal end and a distal end, and includes a longitudinal slot extending from the proximal end to the distal end. The device also includes a line locking member facing the proximal end of the rotor, as well as a tackle securing member and a line centering member facing the distal end of the rotor. Fishing line is threaded through the hollow cylindrical rotor and then looped around the same, forming a uni-knot.

Abstract: A cap device for preventing an airflow streaming from an inlet bore of an abrasion contact tool to a plurality of outlet bores disposed thereabout. The cap device comprises a cap engageable to the abrasion contact tool having an inner surface. A bar formed or attached to the inner surface is provided that is positionable over the inlet bore to prevent the airflow streaming therefrom when the cap is engaged to the abrasion contact tool so as to allow the outlet bores to selectively exert a vacuum airflow exiting therethrough.
