Tool upgrades and skills
Dinkum licences and skill levels matter when upgrading tools. KRAFTON's tool FAQ advises players to get the appropriate licence and skill level, and to revisit Fletch after reaching level 10 in a skill. It also mentions a wandering trader for certain special items.
This does not mean every licence unlocks exactly at level 10. Check the particular activity and current Fletch menu instead of extrapolating one threshold to mining, farming and vehicles. The reviewed support answer does not give a complete point-cost table.
Deep Mining Licence
The KRAFTON old-keys FAQ specifically says you need a Deep Mining Licence and must construct the mine. It then explains why old keys are worth keeping for that destination. This connects a licence, a town building and an item use in a single documented progression path.
Nothing in that answer establishes the exact amount of currency or materials required for every step. If a player has old keys but no mine, the keys alone are not the building unlock. Return to the relevant in-game licence and construction menus before following a detailed mining itinerary.
Breeding and railway prerequisites
Animal Tracks says Animal Handling Licence level 3 or higher enables the Animal Breeding Licence at Fletch. The Egg Incubator recipe becomes available with Animal Breeding Licence level 1. Domesti-Crates for selected wildlife require Trapping Licence level 2 or higher at Irwin's.
For rail travel, the same notes say Vehicle Licence level 2 or higher lets you obtain a Locomotive Licence to craft railway tracks and bridges. The Great Bite patch later calls the Switch Railway Track unlock a Train Licence, which may reflect naming differences across versions. Do not flatten those wording differences into a fabricated universal licence tree.
Costs and missing unlocks
The 1.0 patch also names a Pilot Licence for the person steering a two-seat plane; its passenger needs no such licence. Newer crafting stations and machines have different conditions that should be checked individually. A broad "licences" keyword does not justify claiming a fixed cost for every profession.
The precise current price, point requirements and complete ordering of all licences remain 待确认. The confirmed prerequisite examples above are enough to diagnose several common blocked actions. For a specific activity, follow the linked animal, mine or vehicle guide rather than assuming one progression path fits all.

What players ask
Why is an upgraded tool unavailable?
The official FAQ says to have the appropriate licence and skill level, then check with Fletch after reaching level 10 in that skill.
