I found this easy tutorial on a Russian site. Although I don’t speak a word in Russian, the pictures talk for themselves. A clay extruder will be needed though.
A thicker tude is extruded, which will be in the inside of the cane, and many-many thin tubes that come around the thick one. Then they are twisted and pinned through on the ends. I also used some liquid clay to stick them together and make sure they won’t fall apart. Then bake on a round metal piece and maybe give a shine in the end.
