Some firm but flexible wooden stick.
the best way to find a Ashwood Stick is to cut down an Ashwood Tree. You’ll need to use the “cut firewood” option when using a Firefighter’s Axe, Hatchet or Splitting Axe. The tree will drop Firewood and a single Ashwood Stick. You can also cut off an ashwood stick by holding a knife in your hands and choosing the option “Cut ashwood branch”.
