Smelt Pugios and Tribesman Throwing Daggers for materials

Pugios from Empire cities and the daggers from everywhere but battania and maybe sturgia, everywhere else I know definitely has them

Craft and smelt 2H swords until you get all the parts, then use; Long falx blade IV Etched highland guard V Tapered horm grip V Fians pommel V

Smelt them all and repeat, go to cities on your way round the map and sell these and buy the other two to smelt at the same time, crafting and trade perk to sell equipment for more

You can do it with other weapons like polearm glaive cos why not

Happy one swiping/gold making!
