Hard-to-Find Knowles-Type Patent Jack Plane with Butcher Iron – A Landmark in American Toolmaking.

This rare Knowles-type patent jack plane represents one of the earliest patented woodworking planes in the United States, dating to the mid-19th century. It features a robust 14 1/2″ long body and a 2″ wide Butcher iron, a classic pairing that speaks to its original working intent and enduring craftsmanship.
The Knowles patent, granted in 1827 to Hazard Knowles, marked a pivotal shift in American plane design, introducing cast iron elements to what had previously been an all-wooden tradition. This example reflects that transitional era, with its distinctive form and early manufacturing techniques. The Butcher iron, a respected  maker, further enhances its authenticity and collector appeal.
