Seems like every old warlock has a cane.
They say that old Tom Weir (1599-1670) used to send his down to the corner store—by itself!—to pick up orders for him. The Devil gave it to him at his oathing in place of a familiar, reasoning that this would, for a townsman, be less conspicuous than a live animal.
So, Tom, while we're talking conspicuous....
Weir's infamous warlock's cane was carved from blackthorn, with a satyr's head for a handle. It burned along with its master on Colton Hill in Edinboro, “twisting like a serpent” in the flames. This was taken as affirmation of its diabolical origin.
Well, now.
