Subject: [CR]evolution of chainring bolts

How did the current chainring bolt come into it's current form? The reason I ask is I've skinned my knuckles for the xxxx,000 th time. Yes, the appropriate way to remove or tighten chainring bolts is to put the chain on the largest ring. But what if you are assembling the rings off the bike, outside of the factories what have all sorts of fixtures to hold the inside nut thingy with 2 slots on either side. Each time, I've wondered who designed this type of nut/bolt for that specific apllication, and why?? And how come there hasn't been a more suitable alternative that would make much more sense? Am I crying over spilled milk?
