Comment on I've got a double peen AMA

I’m what the aerospace industry calls a “surface enhancement engineer.” A fancy way of calling me a peener. I mostly work with CNC air blast shot peening machines but the principle is essentially the same as a ball peen hammer.
Basically, hitting metal with hard ball causes little dimples to form on the surface of your work piece. Hit it a shit load of times and you get dimples all over. At the end of the day all those dimples help prevent stress fractures from forming.

Would you prefer us to call you a peener?

Well it is the correct term. It’s also funny
