Who actually enjoys raking leaves? Practically no one ... but that doesn't mean it doesn't have to be done. Luckily, this guy has a secret that means it can be done more quickly. The secret even has a great name: the ROBOHANDLE. Winner of a gold medal for inventions at the 2011 Invention & New Product Exposition (INPEX), the ROBOHANDLE is a tool with one goal in mind, which is to make everyday tools easier to use. While the straight, flat handle can be awkward to use and result in wrist, arm and back pain, the ROBOHANDLE is ergonomic. It harnesses the power generated by your bicep and tricep muscles to utilize any give tool, rather than the weaker wrist and forearm muscles. This simple change increases the available torque by 500 percent to 600 percent.
