Steel Bhuj

Taken all the way down to base materials, one Steel Bhuj is 2 crafting steps deep and needs 3 intermediates — Steel Ingot ×2, Iron Ingot ×1 and Oak Lumber ×1 — which resolve to 3 distinct raw materials totalling 12 units, plus 15 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 674 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 9 Fire Shard, 3 Earth Shard and 3 Wind Shard.

The chain crosses two disciplines — Blacksmith to Lv 35 and Carpenter to Lv 32 — so no single class can finish it unaided.

All 3 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
