Resaws are large band saws optimized for cutting timber along the grain to reduce larger sections into smaller sections or veneers. Resawing veneers requires a wide blade – commonly 2 to 3 inches (52–78 mm) – with a small kerf to minimize waste. Resaw blades of up to 1 inch (26 mm) may be fitted to a standard band saw. Many small and medium-sized sawmills use 1- to 11⁄2-inch band saw blades.
Timber mills use larger resaws to rip large planks into smaller sizes. A typical mill sized resaw blade is eight inches wide and made with 16 gauge steel. Resaw blades can be identified by their straight back, as opposed to handsaws and double-cut blades, which have notched or toothed backs.
