I agree, the one I've used had the spring protruding past the bolsters.Eh, not much. If they're ground correctly, the liner and spring are the focal point, at least on most I've seen. There's typically a subtle angle taking the bolster out of the equation.
Of course, I can pop one with my ring (tungsten carbide) and it doesn't even blink. Turn it around, align the Square with the cap, and off it comes.
French Kate was a real person in the history of Titusville and the early oil industry. She was a brothel madam who worked with Ben Hogan (hence the Drake Well anniversary knives being the Ben Hogan and French Kate, a real life historical pair), both namesakes for GEC models.
Information is sparse, but an internet search brings up many mentions of her. Here's one: http://www.petroleumhistory.org/OilHistory/pages/Wild Side/Hogan.html
