===Safe Way===
Create a [[practice doll]] and equip a shaft. Then beat it senseless for a bit, keeping its damage below 20 at all times. Never, EVER use a true weapon, especially a sword, on a practice doll. It's a complete waste of a good weapon and destroys the practice doll in no time. Not recommended. Equipping a shaft is a good weapon to use on a doll, or use a saw.
===Dangerous (but a heck of a lot more fun) Way===
