Edit - Version 0.0.9E The following information is outdated, This post was created Prior to Version 0.0.9E. Alloys have specific tier, And prices now, The mining and requesting info, in particular, is outdated and wrong.

When you start the game, You have a Copper Hammer - And customers will only buy Copper.
When you get 500 copper coins - You should use that to make a new hammer, It'll make customers ask for almost every metal, but that will be better for the time being than needed to replace your hammer every tier. - Plus you get double production for the price of one. - With the 500c, you can buy one tin ingot and then Toss that into your smelter and then toss a copper ingot in immediately after it -This will make two bronze ingots.
You can then make a Bronze hammer and customers will ask for Tin, But also Iron-Adamantine (and maybe Titanium) - A Bronze Pickaxe (1000C (so its cheaper to do bronze Pick than tin pick) can also get you I think Iron and Adelite veins. - So that too is an option.
If you already have Tin items - It's probably best to break their tool heads off and stick a few of them in the smelter - Then take the resulting tin ingots to get yourself the aforementioned bronze hammer and pickaxe - Then go get yourself the highest ore you can mine. And try to keep three of them at the ready
You can sell Anything underlevel. If a customer asks for Titanium, Sell him whatever you can make the most profit off of.
If they ask for a Shield but Copper tool/weapon - ignore the Copper and just make a shield of whatever you can make the most profit off of - Then Send them packing after you give them the shield - This way they don't get stuck, and you make the most bang for your buck.
If they ask for something more specific than Metal (uncommon grip and topspot hammer head for example) then you have to give them the metal tier they request - if you can't just dismiss them.
All Blade sizes can be sold as spears/polearms - The curved blade looks best on a polearm, with whatever guard you fancy. (Large Blade + any guard + Pole grip) (normal blade/Small blade + any guard (or none) + pole grip)
Don't bother trying to Pawn Bronze, Brass, or Steel items on customers - They've got no price/value for the ingots atm. And Customers will rarely (never that I've seen) ask for them specifically. - This are only really helpful for you.
A Tin hammer will force customers to buy tin or copper
an iron hammer - iron tin or copper
Alloy Bronze - A lot of them... Possibly All/Any
Alloy Steel - A lot (All)
Titanium - (All)
Adamantine - Adamantine or Lower (Never Titanium)
Mithril - Mith or Lower (Never Adama/Titan)
Adelite
Alloy Brass - A lot of them (possibly all)
