I downloaded this picture from GunBroker a while back (forgot I had it).  I don't know who took the picture and can't remember who posted it... but it does illustrate an example of a cracked Krag bolt!

Not many examples out there, it looks like the one on top has a crack through the bright spot from the flash/light. Not bad considering almost 500,000 made, a century plus of use, and with many still being used on a regular basis. Not too many other products have been in continuous use for a century with as few failures.
