This is weird for me. You're not going to believe this but a long time ago I worked in a BMW factory making the rear pillar for the 3-series. It was made of about 4 pieces which were already cut and shaped. I clipped these pieces into a machine which would then spot-weld them together. I would take out the finished piece and load it onto a rack (this is probably all automated now). My qouta was about 480 pieces per shift which kept me really busy. I didn't even know that this shape was called a Hofmeister kink.
