Don't bother with period-correct stuff like stainless. A couple of my friends have gone with ceramic hips. Sort of the hip equivalent of bike's carbon fiber. (Hip: double entendre intended. I was a hippy in the Haight. Rode my 1950 Locomotief around Golden Gate Park. Ripped. Fortunately that's all I have left from those days. The bike I mean.)
