Steel's Delight: For those who use steel tools, relish in your expanded gameplay with a new knife for the fabulous Farmer's Delight.
"Knives are lightweight melee weapons. They can harvest Straw from grasses, and guarantee secondary drops from animals."
Steel must be defined under the tag "forge:ingots/steel". Special support for Immersive Engineering and Simply Steel is provided (for smelting the knife into nuggets).
