These are the jo (staff), bokken (wooden sword), and tanto (knife) used in Aikido practice. I purchased them about 7 years ago and used them about 10 times. Jo (staff): Approximately 127.5cm long, approximately 2.3cm in diameter, weighs about 500g Bokken (wooden sword): Approximately 101.5cm long, tsuba (handguard) 3.3cm, weighs about 500g Tanto (knife): Approximately 29.5cm long, tsuba (handguard) 3.3cm The weight was measured with a scale, so please consider it as an approximate guide. The name on the carrying bag has been erased with a marker. #Aikido #Aikido #Sword #Knife #Staff #Practice
