"Rakes, hoes, potato hooks and scythes were forged from steel back in 1808 by the company that started as The Old Stone Shop. By 1949, it had changed its name to reflect its interest in metallurgical research and development. True Temper was born. At their manufacturing plant in Camp Hill, raw wood and steel come together to create a variety of tools. The largest manufacturer of lawn and garden tools in the United States, True Temper makes shovels, rakes, hoes, posthole diggers, and other tools. The company also owns Jackson Manufacturing, a leader in wheelbarrow production."
I don't know anything about their quality, fit, or finish, but they are a local Pa. company.
Since I've discovered coal, I've been using my grandfather's "foundry" shovel. Funny how the old tools are coming out of storage, and are being used again. There is a bond knowing that my hands hold the same tool used by my grandfather.
