The center punch is for getting ones self out if trapped in a car. Of course if the situation is dire you won't have too much time to dig in the kit and get it out. However I feel it is a useful tool like the multi and mini prybar. I make knives and tools for a living so I carry more in the way of tools than most people.

Although carrying a machinist’s center punch is better than nothing, digging through a Maxpedition pouch while trapped upside down in a river or while your car burns to the ground after a serious collision is not what I would consider an ideal situation.
