Uses = trades before the villager restocks · XP = villager experience per trade · Java / Bedrock % = chance that a villager offers this trade.
A Weaponsmith buys Coal, Iron Ingot, Flint and Diamond for emeralds and sells Iron Axe, Enchanted Iron Sword, Bell, Enchanted Diamond Axe and Enchanted Diamond Sword — 9 possible trades from Novice to Master.
The Grindstone. An unemployed villager that claims a Grindstone becomes a Weaponsmith. Break the block before your first trade to make the villager pick a new profession.
Sell it 15 Coal (Novice), 4 Iron Ingot (Apprentice), 24 Flint (Journeyman) and Diamond (Expert). Each of these trades pays emeralds and gives the villager experience towards its next level.
At Master level a Weaponsmith can offer Enchanted Diamond Sword for 13–27 Emerald.
9 possible trades: 3 Novice, 2 Apprentice, 1 Journeyman, 2 Expert and 1 Master. A villager does not offer all of them — each trade card shows the chance that it is offered in Java and Bedrock Edition.
