I know I read about this in the past but I seem to have forgotten about it again, what do they mean when they say "57-59" Rc (like the S6)? So what's the hardness, 57 or 59? Or is it 58? Or am I just making you guys laugh with my question? <img src="/ubbthreads/images/graemlins/blush.gif" alt="" />

The question about it being differentially or uniformly hardened never really got verified in one of the threads..or did it?
