Abstract: A weight member is removably attachable to a racquet for use during warm-up. The device is a skeletal structure that has a laterally expandable mouth, a throat, and a pair of heads that resiliently converge toward one another. The skeletal structure is formed of a metal bar member of a gauge to match the desired device weight and is coated with a protective outer layer. At least one resilient member can bridge a gap at the mouth and throat. The device is symmetrical in both the X-plane and the Y-plane.

Abstract: A chalk holding device for marking up dry walled walls of a building uses a pole that has a chalk holder at one end wherein chalk is received within the holder and locked in place via a compression ring. The pole may be threadably attached to an additional extension pole on the end opposite the chalk holding end. A light source is attached to the pole either by clamping the light source and attaching the clamp to the pole via another clamp, via adhesion or welding, or other appropriate attachment method, or the light source is an LED ring such that the pole passes through a central opening of the LED ring with the ring attached to the pole.
