To create things, You need Heated ingots ontop of the anvil, they will "snap" into place if close enough, but if they don't snap, they're not in place, and likely you won't be able to do anything.

• to make a 2h weapon. (require 2h grip)
  
  • 2h sword -> Large Blade -> 3 ingots + 2h guard
  • 2h axe -> Large axe head-> 3 ingots
  • Pickaxe -> Large axe head -> 3 ingots -> requires you to cycle through the different variants
  • 2h hammer -> Large Blunt -> 3 ingots
• Polearm (require polegrip)
  
  • Large Blade
  • Small Blade (1 ingot)
  • medium/normal blade (2 ingot)
  • Small Hammer head (2 ingot)
  • Potentially Large Hammer head (I've not checked recently.
    
    • the bladed polearms can be combined with Guards, any guards, and still successfully create an item.
      • I think I tested once upon a time with blunts and found they wouldn't attach if you used guard, But haven't tried recently to verify.
• 1h weapons (obvious grip)
  • Small Blade
  • Medium/normal blade (Requires 1h guard (any))
  • small axe head (2 ingots)
  • Small hammer head (2 ingots, can be changed between Hammer, and Mace-type)
    
    • Mace Type cannot be used by the blacksmith - But can be sold to any customer requesting Hammer PROVIDED... they do not request a specific hammer head.
• Blacksmith Tools
  • The blacksmith can attach and use a 2h Small-hammer Head, This is not an item that can be sold, but the blacksmith can assemble it, and can wield it.
  • The same Goes for pickaxe, You can make a 1h pickaxe - It cannot be sold, but it can be equipped by the blacksmith
  • The same goes for Hatchet, You can make a 2h hatchet - make it look like an normal fireax or wood cutting ax that you might see in stores with a 2h grip - you can equip this, but it cannot be sold like this.
• Saleable Items
  • All Saleable items will and must notify you upon their creation, You'll see this notification in the bottom corner of the screen saying "You created such and such" or something like this.
• Shields
  • Shields are a 5 ingot item, They're a bit of a time consumer, but you can make virtually any quality shield and sell it to any quality customer.
    • Example: You have a copper hammer, and the customer requests for a copper sword and a shield
      • by some twist of miracle, yOu happen to have 5 titanium ingots. You can make a titanium shield, and sell that copper customer, that shield, and he'll buy it... Or at least that was how it was the last time I played. I haven't had a recent shield customer to be honest and took a break from playing again more recently.
  • 3 ingots are used in creating ONE INGOT Items.
    
    • 1 ingot for the Shield Boss
    • 1 ingot for the Wrist grip
    • and 1 ingot for the hand grip
      • These are all in the same 1 ingot category, they're obtained by cycling through the variants (hitting the item another time)
  • 2 ingots are used in the rim, there's 3 or so types of shields, but only 1 of them has like 8 variants. - each variant and type require a hit on the item to cycle through to it.
    • as of Version 9, the anvil and shield are not necessarily ideal for each other, and you will run into difficulties with it falling from the anvil, Do not panic/fret/whatever, Just put it near the top of the anvil and hit it again.
• If I missed any. Sorry. I forgot.
