I found this picture on the Outils Anciens site that Billman frequents.  Quite a few canes with hammer heads, but in the lower left hand corner is a brass cane head that features a hammer and an adjustable wrench.  One wonders how some one came up with the idea.

All those are cool, especially the wrench one. I am a member there but don't contribute since my French is sadly all but forgotten!

Those are pretty neat, my buddy has a couple hatchets that have a baseball ball bat handle on them.
