Historical Background
The Ohio Tool Company was established in Columbus, Ohio, in the mid-19th century and became a recognized American manufacturer of woodworking tools.
The company produced a variety of tools for professional craftsmen, including planes and chisels.
Corner chisels were specialized tools used to create clean, square internal corners in mortises and other joinery. Before modern power tools became commonplace, tools like this were important equipment for cabinetmakers, carpenters, and timber framers.
This example likely dates to the late 1800s or early 1900s, although its exact manufacturing date has not been established.
