Back in the day I used to wear a Tekna dive knife on my pfd when running whitewater. It was considered a rescue device. In theory for freeing a trapped person tangled or otherwise unable to free themselves. I bet very few were actually used for the intended purpose, but mine spread a lot of peanut butter
It would seem even less likely to see use when cycling. I own one, but am highly unlikely to actually carry it on the bike.
