FLINT

Flint sits on both sides of the trading screen: some villagers will buy it from you for emeralds, while others sell it back. That makes it a useful pivot item when you are turning farm output into gear.

Flint appears in the villager trade economy as a tradeable good.

It passes through 4 different professions — Fletcher, Leatherworker, Toolsmith, and Weaponsmith — so several trading-hall layouts can supply it. Flint can also be obtained outside of trading, but buying it from a villager is often faster than gathering or smelting the ingredients yourself.

To buy Flint, visit a Fletcher at the Novice tier (1 emerald, 10 per trade).

To sell Flint for emeralds, bring it to a Fletcher at the Apprentice tier (26 units per 1 emerald), a Leatherworker at the Apprentice tier (26 units per 1 emerald), a Toolsmith at the Journeyman tier (30 units per 1 emerald), and a Weaponsmith at the Journeyman tier (24 units per 1 emerald).

On the supply side, Flint is worth one emerald per 24 units at its best rate (the Weaponsmith). That ratio is what decides whether farming flint for currency is efficient: the fewer units a villager demands per emerald, the more valuable each one is to produce. A buy slot like this can be used 12 times before it locks and the villager has to restock, capping how many emeralds one villager returns per cycle before it must work at its job site again.

On the demand side, the cheapest a villager will sell flint for is 1 emerald for 10 at a time (the Fletcher). Stack multiple villagers offering it, or cure one for a discount, and you can pull large quantities cheaply.

Because Flint is both bought and sold, it is tempting to arbitrage it — but villager buy and sell prices never line up in your favour, so the real value is convenience: convert spare flint into emeralds with one villager, then spend those emeralds on gear elsewhere.

Every Flint trade follows Minecraft's standard supply-and-demand rules. A trade can be used a limited number of times — 12 for the slot in question — before it greys out and locks until the villager restocks. A villager restocks up to twice per in-game day, but only if it can path to its job-site block and "work" there, which is why a trading hall must leave the workstation reachable.

Buying flint repeatedly nudges its price up: heavy demand temporarily inflates the emerald cost, and the price drifts back down over time or resets when the villager restocks. Curing the villager from zombie form, or triggering the Hero of the Village effect, applies a discount on top of that, which is the cheapest way to acquire flint in bulk.

When you sell flint to a villager, completing that trade is what grants the villager career experience and pushes it toward its next tier. Spreading sales across several villagers of the same profession multiplies both your emerald throughput and how quickly the hall levels up.

One caution: the first trade you complete with a fresh villager permanently locks its current offers, including the flint slot at whatever price it rolled. If you are chasing a specific price, decide before you trade, because there is no re-rolling a villager once it has done business with you.
