It came out of an aviation box covered elsewhere here, so it had a some sort of. One thing I have learned to hate from avation is all the tools in the box need to be run across my demagnetizer. Damn tool tracking.I'm guessing it was a specific wrench for some fairly simple homeowner-grade tool.
Others here will know more than I, but I'd be shocked sh*tless if any aviation-spec tool didn't have control numbers on it that identified all kinds of things.
