It's pretty simple and probably stupid. I assume others have easily thought of this. But if we're talking about peasants and magic I think that indestructable tools would be almost a must have. The hoe that never breaks no matter how many fields you sow, the hammer that can forge as long as it has someone to use it. And conisdering most set-ups say that magically enchanted weapons are auto-indestructable to standard means(i.e. rust, wear and tear) indestructability doesn't seem like it'd be so hard to put on a tool.
