Crosscut saw. If youâre cutting across the grain of the wood, youâll want to use a crosscut saw. The teeth on a crosscut saw angle back and have a beveled edge. The teeth are also much smaller than those on a ripsaw. This design allows the saw to act like a knife-edge that cleanly slices through the woodâs grain.
