An apprentice or assistant would be cool. Someone to do some of the work, like for example: mining for ore on every cycle, of course you'd have to make the pick and he could only mine the appropriate ore with that pick; assembling items by handing him the appropriate parts (if you gave him a guard, two hand grip, and one hand mallet, naturally he wouldn't be able to make anything. Give him a polearm grip and a small blade however, he'd make the polearm), and perhaps after he finishes assembling the part, automatically taking it to the customer. Traveling blacksmiths or merchants that teach you new weapons (Egyptian Kopesh, Japanese Tanto or Dikatana, German Halberd or Zwiehander, Chinese Dao, etc... ) and alloys, such as Damascus steel or just carbon steel, nickle iron (meteoric iron), amalgams for gilding weapons and shields, or various other steel alloys, like cobalt steel.
For historical accuracy: Historically speaking, swords were the most common weapon for self defense. Axes, maces, and hammers were used predominately in war. Maces were used to crush and weaken plate armor. Hammers, such as the maul, were also used to crush the enemy, but were often paired with spikes for uses against thinner armors. Axes were found among the high class rabble outside of war more commonly than hammers and maces, but not quite as common as the sword, as they were less versatile and it is often frowned upon for a nobleman to carry any weapon other than a sword. They were designed to cleave through enemies limbs, not for self defense per sey. The polearm form of the battle axes, such as the sparth axe, were primarily used in war due to how hard they were to wield. However, many places in the medieval time banned peasants from carrying weaponry. In this case, axes were more common, because they had a domestic function, axes were often not included in this ban. Axes are also cheaper to make than swords, and ultimately lighter. Battle axes were not included in this, as they were made for battle.
In short, axes and swords should be the most common weapon requested to be made, in that order because axes had a higher demand due to the domestic use. Then one hand hammers (for their domestic use), followed by the polearms, and the remaining two hand weapons as well as the other blunts (the flanged mace and morningstar). Shields would be requested as commonly as the polearms and they other war weapons.
These last two paragraphs are, of course, only important if you wanted it to be more historically accurate. I see no reason as to make it this game accurate, and I'm not requesting it. I'm simply informing you in case you wanted it to be.
