There are 5 tiers of weapons and tools - Iron, Bronze, Silver, Gold and Diamond. Each tier does better damage than the previous, so naturally the devs made it so that every biome has a “base tier”, where the weapons and tools in that biome are most likely to spawn in that tier. The exact variations are discussed in the page Probabilities of Various Stuff, but this page is meant to just document the levels and their base tiers.
