The katana is a long curved blade with a chisel like point. Because the katana is a single-edged sword, it is also referred to as a back-sword, meaning it had an unsharpened edge or back, rather than a sharpened edge on both sides. Because of its curved shape and chisel point, the katana could be used as both a slashing and thrusting weapon.
