There was also a rumor that 'if you have a sword, the GHQ will come to search with a metal detector,' so some swords were hidden in the ground, which caused them to corrode and they were ruined, some were broken to make a short one which is shorter than the length of the those that were prized by collectors, and some people discarded swords on their own, and so on and so forth.
また、「刀があるとGHQが金属探知機で探しに来る」との流言も飛び交い、土中に隠匿して、その結果刀を朽ちさせ駄目にしたり、回収基準の長さ以下になるように折って小刀としたり、自主的に廃棄するなどした例は枚挙に遑がない。
