I restored "1930s Irwin Antique Screwdriver & Estwing Ball Peen Hammer" in the video. "Made in USA" Swedish immigrant Ernest Estwing was a self-taught engineer who started as a six-cents-an-hour machinist before eventually striking out on his own in 1923. His big idea: Hammers forged from a single piece of steel would be stronger than the traditional wood-handled models. He developed prototypes in his garage and then patented his "unbreakable" design. In 1884 Charles IRWIN owned a pharmacy in Martinsville, Ohio. A local blacksmith who was a customer of Mr. IRWIN's came up with the idea for a solid center auger bit. He sold the rights to this invention to Mr. IRWIN and a year later, after patenting the Auger bit, Charles IRWIN, along with four other business partners formed the IRWIN Auger Bit Co. About four decades later there was another blacksmith with an idea, this one in the small town of DeWitt, Nebraska. William Petersen was a Danish immigrant who invented the first locking pliers in his blacksmith shop, and began selling them from the trunk of his car to farmers and people in surrounding towns. He patented his new idea and called it Vise-Grip.It was the beginning of what would become two tool industry leaders, joining forces to create one industry giant. In 1993 the company's histories would converge. Petersen Manufacturing, which changed its name to American Tool Companies in 1985, acquired the IRWIN Tool Company.
