Henry David Thoreau wrote in 1848 “I suspect that it was made according to an aboriginal pattern” referring to a crooked knife being used by an Indian to fashion a canoe paddle. He had reported that he had seen other native Americans as well as white woodsmen using them. The crooked knife was used in the wilderness as a lightweight one handed drawknife. A tool that could accomplish almost any woodworking need.
