Behold this mighty shillelagh, the Burl of walking Earth
Shillelagh explained: https://en.wikipedia.org/wiki/Shillelagh - Blackthorn (Prunus spinosa) taproot.
Is a shillelagh so precisely defined? I thought any good thwomping stick could be a shillelagh in the hands of a stout Irishman.
I had thought it was a briar tap root, but realize as I write this, that the briar tap root is used for making pipes. Being quite clearly a fan, but no authority, I hit up wikipedia, like ya do.
Very Nice!
A very nice stick
