My wife is pretty great at giving gifts. She always remembers some fragment of a conversation where I mentioned liking some obscure book, food, tool, Bruce Lee movie, etc. During our senior year of college she really outdid herself. We were watching The Natural, where Robert Redford makes his own baseball bat after lighting strikes a tree on his farm. Somehow this lead to a discussion on alternate materials for bats, tradeoffs, wagers, the usual between two engineers.
I concluded that a stainless steel baseball bat would be incredibly cool, although ridiculously heavy, and didn't think anything more of it. My wife, however, went to work. At that time she had a job in the machine shop of the mechanical engineering department. Usually this meant making test fixtures and prototypes for grad students and professors. That November it meant turning a cylinder of solid stainless steel into a baseball bat.
I'm told it was the talk of the shop, as ridiculous projects usually are. After many hours on the lathe cutting & polishing she managed to surprise me with this beast under the tree. The best part is keeping it my office. People assume it is aluminum and try to pick it up to swing it.
It weighs about 30 pounds and is the best Christmas gift I've ever received.
