I honestly feel like they missed a nice opportunity for a third-tier Maul weapon. A Black Metal Maul (or Sledge) could have looked so awesome.

But yeah, we definitely need a higher-tier tool set. While there is a Black Metal Axe, there definitely needs to be a Pickaxe. I'm also of the opinion that the Hammer needs at least a Copper and Iron upgrade.. maybe to allow for more flexible building/world-shaping options. (Also the Hoe, but yeah.)

But anyway.
