This mod will allow you to craft sticks from firewood.
Two whole sticks from one firewood.
Not one stick.
Not three sticks.
Two whole sticks.
From a single piece of firewood.

No if's, and's or but's.
No more, no less.
Two sticks from one piece of firewood.

Should you have different opinions on the quantity of slender wood pieces garnered from the cutting of a single piece of flammable material, you may manually edit the recipe in the mod's json folder.

This may, however, be seen as heresy.

This mod is purely server-side, meaning nobody else needs to download this mod except for the server hoster should they use it.
