For straight XP grinding these are the usual crafts to check against your server’s mat prices.
Heraldic shields (100 wood, 5 silver): 267xp.
Wooden bucklers/Wooden mallets (30 wood): 60xp.
Stone hammers (30 stone, 20 wood): 110xp.
Maces (30 stone, 30 hematite, 15 wood, 10 copper): 207xp.
Flint daggers (8 flint, 5 wood): 22xp.
Stone road kits (20 stone): 37xp.
Road kits can give a bit less, but have the benefit of being a pure stone sink, plus they’re useful.
I have a list of all crafts XP for the Wiki but I’m not sure how to organize it yet.
