I was trying to make a "wand" when i noticed that stat.useItem.minecraft.stick doesnt work. i have looked through similar bug reports and it said it counts as a "use" when you left-click. apparently that isn't the case. Left or right click, nothing happens.
stat.useItem
tracks an action that uses up durability or a right-click of an item that does something. Therefore, sticks have no "use."
