  My time has come.

  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.

    Soft face is exactly what it says, it’s got soft rubber faces, basically just a shrunk down rubber mallet. Use it on things you don’t want to leave marks on.

    Double peen is basically just a soft face except one side is like a hard epoxy like material. Harder than the rubber side, still softer than a metal head would be.
