Abstract: A tool for aiding marking or cutting is described. A V-shaped member having an edge formed at an exterior apex of the V for guiding a marker or cutting tool. The exterior surfaces of the V-shaped member may have a material applied having a higher coefficient of friction than that of the V-shaped member. The edge at the apex of the V may have two substantially planar surfaces, each of which forms a complimentary angle with the interior apex angle of the V, or a thin metal portion formed in the exterior apex of the V so that an edge thereof protrudes sloping towards a surface on which the tool is laid. A graduated scale may be applied to an exterior surface of the tool at a location near the apex.

Abstract: A water cooler caddy device for use in conjunction with a water cooler or other beverage dispenser. The water cooler caddy has an arcuate inner surface as an interface with the water bottle and is sized such that it may be placed over the water bottle and slid down so that it either rests on an upper surface of the water cooler, or is supported by the side of the water bottle. The water cooler caddy may have a gap in the circumference so that the radius of the inner surface may be temporarily increased to facilitate installation. Partitions are used to form compartments to contain service items.
