Adamantite Hatchet

Taken all the way down to base materials, one Adamantite Hatchet is 3 crafting steps deep and needs 4 intermediates — Adamantite Nugget ×2, Amphiptere Leather ×1, Hardsilver Ingot ×1 and 1 other — which resolve to 8 distinct raw materials totalling 27 units, plus 27 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,123 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 10 Fire Crystal, 9 Wind Crystal, 5 Earth Crystal and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 60, Leatherworker to Lv 58 and Goldsmith to Lv 56 — so no single class can finish it unaided.

7 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00) and Darksteel Ore (1:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Hardsilver Ingot has the widest use: 117 recipes call for it, spanning seven of the eight crafting classes.
