In this video I explain the history of the Ohio Tool Co., one of the major plane makers of the 1800s, while I restore one of their Scioto Works jack planes. Despite the company’s claim that they were established in 1823, I found research by the Mid West Tool Collectors Association that showed that the 1823 date referred to the predecessors of the Auburn Tool Co. (which Ohio merged with in the 1890s) and not Ohio Tools itself. 1823 is just a date they used in advertising to make them look older than they really were. Auburn and Ohio tools also used the Owasco Tool Co. brand and made Thistle Brand irons.
