发明名称 Prospector's shovel and crevicing tool
摘要 A prospector shovel and crevicing tool (10) having a first scoop (12) and a second scoop (14). Both scoops have a rigid tubular sidewall (16, 24), a closed end (18, 26), and an open end (20, 28). The closed ends (18, 26) abut each other to form one tool that has a scoop on each end that can be used to hold gold ore or to crevice rocks and other debris. Each open end (20, 28) of its respective scoop forms an angle ( PROPORTIONAL , phi ) with its respective sidewall (16, 24). In preferred form, the first and second scoops (12, 14) angularly abut at angle ( theta , theta ') to provide better leverage for scooping in conjunction with the prospector's use of the second scoop as a handle. The diameter (d1) of the first scoop (12) is larger than that of the diameter (d2) of the second scoop (14). A hook (42) having two ends (44, 46) is fixedly attached to the first and second scoop in order to provide the prospector a way to carry tool (10) on the prospector's belt or on one of the prospector's belt loops or other equipment. A neoprene handle grip (48) surrounds the sidewall (24) of the second scoop (14) for ease in handling.
