Baton used for relay race. It's shaped like an old-fashioned grenade with a handle, but it is a device with an electronic detonator inserted into it, which will never explode if it can be passed on to the next runner within a certain time.
リレーに使用されるバトン。旧式の柄付き手榴弾のような形だが、電子式雷管を挿入した製品で、一定時間内に次のランナーに引き継げれば絶対に爆発しない。
