Made in U.S.A. Whiteside (Actually Whiteside Machine) is regularly rated as #1 for cut quality and #1 for value by Fine Woodworking magazine.
Whiteside Machine was originally a machine shop, many decades ago. They were machining precision router bodies for a customer. The customer went broke leaving them sitting on the router bodies so they decide to finish them and sell them. This is a real All-American story of courage, resourcefulness, guts and just plain stubbornness.
Decades later they are still stubborn about absolutely top quality and beautiful tools.
