An inventor with 25 years' experience, Dan Brown launched Chicago-based LoggerHead Tools and started selling his first products last summer. The Bionic Wrench comes in three sizes, which can collectively adjust to and grip as many as 38 different-sized nuts. Brown has won several design awards for the wrench, which is slip-proof, does not strip the heads of nuts and is guaranteed forever. The company's expanded line now includes a universal multitool called the ImmiX. A cutting tool for pipes comes out later this year.
