High Durium Awl

Taken all the way down to base materials, one High Durium Awl is 2 crafting steps deep and needs 3 intermediates — High Durium Nugget ×2, Dwarven Mythril Ingot ×1 and Horse Chestnut Lumber ×1 — which resolve to 5 distinct raw materials totalling 22 units, plus 46 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 917 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 31 Fire Crystal, 8 Wind Crystal and 7 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 81 and Carpenter to Lv 81 — so no single class can finish it unaided.

All 5 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
