as far as i know it just falls under craft (weapons, armor, bowyer, fletching),a dn you fluff what the weapon's appearance is. it doesnt change the weapons statistics any, so a rapier with a basket hilt is still a rapier.
there's weapon accessories in the adventurer's armory (the weapon cord sees a lot of use in gunslinger circles), if memory serves. you could craft those with the weapons and offer/use them as a package deal i guess.

Beware, it takes a long time to make masterwork items. And working with special materials like mithral and adamantine takes even longer.
I have a player in my campaign playing a blacksmithing fighter, and, because of all the inconvenient interruptions, it has taken him almost seven weeks to create a masterwork bastardsword.
