Artisan Crafting and Adventures

Hey all,

I just made a knight flavoured as a samurai style character and aim to tackle all the prewritten adventures with my brother's ranger/scoundrel. Is there a particular order we should approach them?

Additionally, are there rules for the artisan crafting martial ariltist weapons? I'm a while away from martial arts but was curious about katana forging or throwing weapons.

Thanks!!

Kind regards,

Ethan
