Characteristics
Overview
A sharp butcher knife. Extremely good at harvesting flesh from both dead or alive bodies.
Do not go looking for it at the research table. It cannot be crafted or researched at all, so this knife only reaches you through loot or a trade, most often from Halloween event loot.
Once you have one, give it the farming job. The game's own text calls it extremely good at harvesting flesh, and a worn-out one recycles into metal fragments, so it never goes to waste.
The typical moment: a boar wanders up to your walls in the evening, you drop it with a couple of arrows, switch to the butcher knife and carry back the pork and leather. That is what it is for. If the trip could turn into PvP, take the combat knife instead, since that one is built for fighting and attacks while you sprint.
Next to the bone knife it is a clear step up, and one you never have to hunt bones for.
Recycling
At power grid stage 2 a green recycler works at 60% instead of 50%. Yields depend on the recycler.
