butt hook - embossed with Wirkkala |
Provenance |
Oscar Wirkkala invented and developed the high lead method of logging. This skyline (or "spar") method, ideally suited for steep terrain, revolutionized the industry. He also invented important pieces of that industry's machinery used during the first half of the 20th century, including the ubiquitous choker hook. His first patent was granted in 1917, and was for a four-drum donkey engine used in his high lead logging system. In the following years, several of his patented devices were manufactured, under the Wirkkala brand, at the Willapa Harbor Iron Works in South Bend. A few of his patented inventions were still in manufacture well into the second half of the 20th century. |
