Making good use of Master Tinker (Exotic Weapons)

[SangoProduction]

Gnomes experiment with all manner of mechanical devices. Gnomes with this racial trait gain a +1 bonus on Disable Device and Knowledge (engineering) checks. They are treated as proficient with any weapon they have personally crafted. This racial trait replaces defensive training and hatred.

Gnomes have this alternative racial trait. It's pretty neat. Conceptually at least. Not a lot of things that really matter in the slightest. But still.

Assuming that you've got the skill points to just have all the crafts (which I do), what are the most notable weapons that you can suddenly be proficient in?

Spiked chains? Two handed swords if you don’t have that proficiency already? Ditto Mighty Composite Long Bows?

Would siege weaponry count?
