High Steel Head Knife

Taken all the way down to base materials, one High Steel Head Knife is 2 crafting steps deep and needs 3 intermediates — Beech Lumber ×1, High Steel Nugget ×1 and Koppranickel Nugget ×1 — which resolve to 5 distinct raw materials totalling 15 units, plus 14 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 730 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 9 are burned by the intermediates, so the real crystal cost is 6 Fire Crystal, 6 Wind Crystal and 2 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 61, Carpenter to Lv 61 and Goldsmith to Lv 61 — 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
