Daggers, axes, knives, hammers aren't used up while crafting. Just the item (branch, log, animal hide, etc)
Think about what you just wrote for a second, and then wonder why I specified / was testing
only daggers here.
Hint:
log + sharp metal axe = firewood + axe
branch + sharp metal thing = stick with sharp pointy tip attached to it, otherwise known as a spear
They're not the same class of crafting. If this is the case for
all daggers, then they're in the wrong type of crafting subcategory. i.e. should be in the class where both items are used up.
However, it's still the case that a quest object shouldn't have the vanilla item tags, in case of selling etc.
