Invent Creation Requirements

[DizzyDogg]

we have the concept of requirements in performing actions (weight and sharpness for chopping a branch). We also have the concept of required tools. However, the game needs to combine those two concepts in order to create requirements in crafting. For example, required sharpness to cut hide into cord ... Currently, a handaxe can make a cord, but a real axe cannot. silly me.

recipe for cord should say, I need a hide and access to something sharp. If I want to sharpen a stick, I should need a stick and something sharp. not sure what to do when the ingredient needs to be sharp ... like, something sharp as an ingredient for an axe.
