The Practice Axe (訓練用の斧 Kunren-yō no ono, lit. Training Axe) is a rookie Axe that appears exclusively in Fire Emblem: Path of Radiance. This axe only appears in the Prologue, and is wielded by Boyd during a practice sparring session that he engages with Ike. The Practice Axe is incapable of performing critical attacks.
The Practice Axe is analogous to the Trainer Sword.
