A skewer is a fairly strong weapon with good speed as well as a combo that makes it insanely fast for a second. It can be crafted on an assembling table as a level 3 recipe.
It's overall better than the kitchen knife in stats although while the skewer's combo is stronger it also last for less time. It's also rarer to find than the kitchen knife, and due to the high demand for wood often not crafted in favor of scrap metal based weapons.
