I know this sounds strange, but try looking at "jersey cabbage walking sticks".
It could be a cabbage stalk with all the knobs.
The Jersey cabbage is used to make sticks and canes. The round handles are formed by starting the plant in a pot, and when it grows to a certain size, the pot is turned over on its side. The cabbage stalk wants to grow up, and where its stalk bends, a permanent curve is formed.
Of a variety of Kale - the stalks are sturdy and look like wood when dried!
These suckers get TALL!!!
