A resaw includes a frame having at least one head. The head includes a horizontal mounting beam with four wheels operatively mounted to the mounting beam. The wheels comprise an inner pair of wheels and an outer pair of wheels. The centers of the inner wheels are vertically offset from the center of the outer wheels. A band blade is mounted about the four wheels to define a first blade portion and a second blade portion which are spaced from each other. A single head can simultaneously make two slices in a cant to cut two or more boards from the cant. The inner and outer wheels can be moved as a unit relative to the path of travel of a cant and the inner wheels can be moved relative to the outer wheels to enable adjustment of the thickness of the boards cut from the cant. In variations, the resaw can have two heads, and each head can have one, two, or more band blades. With a two head resaw, four slices can simultaneously be made in the cant. Where each head of the two head resaw has two band blades, eight slices can simultaneously be cut in the cant.
