A man who told police he was wielding a samurai sword in a WA park because he was training to become a Jedi knight will have his weapon destroyed.

Guy Graham Jones was also ordered to pay $200 and put on a six-month conditional release order when he appeared in the Bunbury Magistrates Court.

Jones was charged with possessing a controlled weapon after he was seen waving the 70 centimetre sword in parkland near Big Swamp in April.

He claimed he then threw it on the ground in an effort to break it and make it less dangerous.

Jones previously told the court he was joking when he told police he was in Jedi training.

Police said the sword will be taken to the tip and crushed by a bulldozer.
