Exactly. My mother-in-law is an avid golfer and had a temporary condition requiring the use of a cane. Friends of hers got her a driver (the largest golf club), modified to have a bent handle and some rubber on the head to serve as a cane. She was surprised to find that the TSA wouldn't let her through security carrying what most would agree is effectively both a golf club (not allowed) and a cane (allowed). (I was surprised that she was surprised.)
