There is a renaissance of historical "Irish" martial methods
I don't think it's a 'renaissance' with these guys, nor do I think it's historical with them as their regiment dates from the 17th century and it's something they've always done. I doubt it's as finessed as training elsewhere but it's very realistic. They will even use it outside the camp gates because I have only met one other regiment ( The Black Watch) that fights as much as they do, if they run out of people to fight they will fight among themselves. Never though unlike other regiments have I ever been threatened by them though.
A 'cane' in the UK is specifically a bamboo cane, usually used to spank children ( historically) and willing adults, sometimes used as a dandy's walking stick.
