Atha Tool Co.
Newark, New Jersey
Blacksmithing tools, hammers, railroad tools, stoneworking tools, especially noted for farrier tools and mining tools
There is some contradiction concerning the ontogeny of this particular company--contention exists concerning whether or not it was formerly Newark Steel Works. Benjamin Atha, who was part of the Newark Steel Works, incorporated the company in 1891. It may have been established as early as 1875. They bought out Emmett Hammer Co. in 1884, Hartford Hammer Co. in 1892, Eyeless Tool Co. in 1897, Clark Edge Tool Works in 1897, Buffalo Hammer Co. in 1898, and Yerkes Tool Co. in 1898. Finally, in 1913, Stanley Rule & Level Co. in 1913 bought them out.
