One of my characters is nearly 19 and just found his first Masterwork Broadknife- in fact, he found TWO of them. Traveling from Kuikka lands down to Reemi lands, the only area he'd never been to, was very rewarding. His previous excursions were so exhausting that he'd just never gotten so far to the southeast.
Carrying a dozen furs, a handful of weapons, and 50 arrows for barter (and as it turned out, his Fine Northern knife and a linen shirt), he managed to trade for, at Masterwork quality, a broadaxe, a carving ax, the two broad knives, a small knife, and a shield. He also traded for a big boar (it just seemed like a must-buy!), a big dog, and a BIG BULL! In addition to the foot wrappings, for the coming cold, he bartered for enough dried and smoked fish and meat along the way to complete his trek. He'd found 37 Reemi villages and there was still a bit of their lands left to explore!
In the end, he returned home a week before winter with only 3 furs and none of the trade weapons left. His barn is looking pretty crowded with 5 dogs, 2 cattle, a deer, and a boar. All in all, the most successful trade trek I can recall.
