Stainless on Stainless has a tendency to "gall" this galling can be avoiding by ramping up the carbon content of the stainless and often that leads to fairly brittle parts. http://t0.gstatic.com/images?q=tbn:ANd9GcTIc74Zq9xoUuJszRTEm_IJeEKV6S8i17tFyyulmvL1vC-fg_LopoOc4PI1 It happens.
That sucks. Many of my baby's are stainless. Stainless rocks.
