In terms of sheer function count, the Chinese-designed Shen Ao line of shovels blows them all away. The latest, the 3.9-foot (1.2-m) Z3, uses Shen Ao's modular handle and multipurpose blade to light up camp, cut wood, start fires and charge your phone. And it can even dig a hole

Similar to AceCamp, Chengdu Duoji Outdoor Products Co realized that it could add a lot more tools to the basic shovel if it relied on the handle for storage. But rather than just storing a few extra items inside a hollow handle, Chengdu broke the handle up into multiple threaded modules. It then expanded that design out into a lineup of shovels of different sizes and functions. The DG is pictured at the top, and the larger, newer Z3 is pictured and described below.
