A golf putter has a club head with a golfer's sighting device in the form of an elongated prism positioned at the top of the club head and aligned with the intended location of ball impact on the club head putting face. An elongated colored strip is disposed in or under the prism and appears maximally wide when viewed from above the prism in a vertical alignment plane which includes the impact spot and the upper edge of the prism, thereby indicating that the golfer's head is properly positioned over the club head. The indicator can be used during actual play and/or, in conjunction with a pivotable shaft, to select the optimal angle between the head and shaft in fabricating a custom putter. An aluminum or other oxide coating on the club head provides the putting face with a greater friction and facilitates adherence of a material having low friction characteristis, such as TEFLON, to the bottom surface of the club head. The edge between the putting face and bottom surface tapers upwardly toward opposite ends of the head from the general location of intended impact with the ball to reduce the likelihood of erratic putting strokes due to unevenly cut grass.

The club head of a golf putter has a substantially flat bottom surface to facilitate alignment of the putt and is symmetrically weight-balanced that it's heel-to-toe center to reduce torque effects and lower its center of gravity. The weight balancing is achieved with a dense sole plate having an elongated intermediate section joining two mass-concentrated heel and toe ends. A less dense body portion provides a soft putting face and has hollowed portions to further lower the center of gravity and concentrate the club head weight at the heel and toe. The front corners of the bottom surface are cut away to reduce scuffing during a golfing stroke. A sighting device on the club head facilitates alignment of a golfer's line of sight in a vertical plane which includes the golf ball, the club head "sweet spot" and the putting target when the golfer's eye is positioned above and rearwardly of the club during alignment of the putt. The sighting device includes a rectangular recess in the upper surface of the putter and strategically located sighting lines on the upper surface and in the recess. The heel-to-toe center of the club includes the center of gravity and the "sweet spot" and is coraxially aligned with the club shaft.

A fish lure, simulating an earthworm or other annelid, includes a clitellum disposed intermediate its ends and eccentrically weighted relative to its central longitudinal axis such that the underside of the lure is weightedly-biased to face downward whenever the lure is in a body of water causing it, when falling to assume a U-shaped, life-like position. A paddle at the tail end of the lure causes the lure to move with a life-like wriggle as it drops through water. A lip proximate the head end of the lure likewise imparts a wriggling motion to the falling lure. The lip may be replaced with a medusa-like collar that opens and closes as the lure is drawn through water by a fishing line that is alternately pulled and relaxed.
