Smithy's hammer Quality = (AvgMetalQ*3 +AnvilQ)/4 softcapped by sqrt(Strength * Smithing)
So at this level, make sure your hammer isn't going to be capped by your sqrt str*smithing, if possible with a bit of extra there in case the anvil is superfantastic (highly unlikely, but at this stage of the world you never know). Make the hammer. If it comes out lower q than the input iron, put 'new anvil' on your shopping list, otherwise just remember to keep an eye on it f your base iron q goes up (with better kiln, charcoal, smelter etc).
Which reminds me that I forgot to put 'build finery forge' on that list of things to do with iron. So yeah, you'll want one of them.
