The Rich-Con brand of tools was one of the trademarks of the Richards -Conover Hardware Company of Kansas City. Established in the late1850s as a local wholesale distributor of hardware and steel products, Richards Conover grew exponentially as the US migrated west. The company went through a number of iterations and location changes over the ensuing 150 years but products always focused on wholesale and mail order household goods, hardware and tools for home and farm.
Can't argue with the performance of this 100 year old.
Rich-Con was one of the few companies that stamped or etched their logo into the side. The other that comes to mind is the Zenith brand by Marshall Wells Hardware of Duluth.
