It's actually a misconception that the tool was ever for catching or breaking swords. While possible, it could be dangerous to try since the tine is so close to the hands.
That first Jitte profile I posted is actually a direct lift from the wikipedia page. It's a style of martial arts and not an object. WIKIPEDIA
page. Even the description was similar and calls it a style of karate. That would make it a concept and not an object.
profile that I made a while back is an object that is used in that style of martial arts. While the name Jitte is sometimes used, Jutte is more appropriate. Jutte translates into "Ten Hands" Ju in Japanese means ten.
