 Are you after the Tufftriding ? I would be too, as it is remarkably scuff resistant in emergency situations, and can improve the fatigue live 3 to 100 X. 

On the original Spyder crank a better steel was used as well as Tufftriding.  Don't know about the steel on later non Tuff-tride cranks.

Use a sharp fine file (but not your best file) to kiss a crank shoulder.  The file will skate across the hard surface with out digging in.
