The Practice Katana (居合刀 Iaitō, lit. Iai Katana) is a Katana that is introduced in Fire Emblem Fates. Like its name suggests, the Practice Katana possesses moderate Might, meant more for practice purposes instead of combat ones. Offsetting this attribute is the fact that the Practice Katana boosts its wielder's Speed, although this comes at the cost of a reduction in both Defense and Resistance.
An Iaitō is a modern practice sword that lacks a cutting edge. It is used to practice the art of Iaido, a Japanese martial art that uses smooth and controlled motions to attack the opponent, remove blood from the blade, and then sheath it back into the scabbard all in one swift action. The trademark swift movement of this martial art is referenced in the weapon's special trait of boosting its wielder's Speed.
