it's still a mystery to me in the current crafting system, why, if I made a club out of iron, then I can't figure out how to make a club out of steel? Is there some fundamentally different approach? or what about a pickaxe? also, different technologies? if you introduce a new system for leveling up crafting levels in A21, it’s better to let any tool be made immediately after leveling up the basic skill, but the quality, resource costs for creating and repairing will increase depending on the books you read. I may have to do this mechanic myself later, unfortunately, so that it would be more pleasant to play.
