When does repairing a worn tool stop being cheaper than making a new one?

If each repair makes the tool a bit weaker, the cheapest choice changes over its life. This entry shows how to work out the real cost per use and when a sensible player stops repairing, so you can tune repair prices.

Why this works

Each repair buys fewer uses than the one before, so the cost of a use rises over the tool's life. A sensible player repairs only while that is still cheaper than a new tool, which is what sets the real price.

When not to use it

Skip it when tools break outright, when a repair needs rare parts, or when the new tool is better than the old one. Then the choice is not about price alone, so compare the tools on what they can do.
