What exactly were blackjacks (the club) made from? I recall seeing pictures of some a while back (I can’t remember where) and I know some were flexible, like a sock with some thing hard (rocks, wooden balls, etc.) put in it. I was wondering about the material it was constructed from.
Would getting slugged by one really just knock someone out like in the old movies and comics, or would the blow just wind up killing you?
Also – can you purchase such items? Where? What about fake blackjacks (that wouldn’t cause harm)?
Any info would be appreciated!
