A Resaw is a large bandsaw 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" (52 - 78 mm) - with a small kerf to minimize waste. Resaw blades of up to 1" (26 mm) may be fitted to a standard bandsaw.
Timber mills use larger resaws to rip large planks into smaller sizes. A typical mill sized resaw is eight inches wide and made with 16 gauge steel. Resaws can be identified by their flat back, as opposed to headsaws and doublecuts which don't have a flat back.
