Hard Practice is Mitsurugi's joke weapon in Soulcalibur IV. It can be bought in Character Creation for 11,800 Gold after completing Story Mode with Mitsurugi. Unlike most joke weapons in SCIV, this one does not have a native skill. It returns as Mitsurugi's joke weapon in Soulcalibur V.
Some Soulcalibur fans don't really consider Hard Practice as a joke weapon due to the fact the joke weapon is actually a shinai, a kendo practice sword. However, it is the only weapon Mitsurugi uses in Soulcalibur IV and Soulcalibur V that isn't made of metal.
