the handshake dilemma

I used to have this really nice hand-carved cane that I got in a little shop in a town in Indiana.  Sadly, I left it on top of my car (I think) on Varick Street -- please let me know if you see somebody walking around Soho with it.  One thing I liked about it was the knob on the top so I could palm it with my little finger and then sort of shake hands.  I have yet to find a solution to this dilemma.  I use a cane with a strap so it can dangle while I grip, but that's pretty awkward.  Is a fist-bump okay for a 50-something guy from New Jersey?
