I am on iron tier right now, I have an iron knife, and use it as my main weapon, but it breaks if i do a mission where I need to fight lots of enemies, normally I can use a pickaxe, or axe to deal less damage and tank some hits, but when fighting a bear or multiple wolfs, I cant risk that, and then while fighting my knife will break and I cant skin and get the meat of animals I just killed, and then another issue is when I was on bone tier, I could easily repair it with bones in my inventory, but with iron knifes I would need an anvil to do so, and they are too heavy to carry, what can I do in this situation??
