Pugil stick

[1] The pugil stick is similar to a quarterstaff or Japanese bo and may be marked to indicate the end that represents the bayonet and the one that is the rifle butt.

Dr. Armond H. Seidler, of the University of New Mexico, invented the pugil stick training method during World War II.

Some pugil sticks are made with integrated hand guards to reduce the potential for injury.

Military procedures for pugil bouts are often detailed, with United States Army and United States Marine Corps both prohibiting pugil training by anyone who has recently suffered concussion of the brain, lest they suffer traumatic brain injury, or has had a tooth extraction within the past 24 hours.

The name "pugil stick" is a neologism from the Latin noun pugnus (fist), the source for other English words such as "pugilist" (boxer) and "pugnacious" (eager to fight).
