Hardsilver Round Knife

Taken all the way down to base materials, one Hardsilver Round Knife is 3 crafting steps deep and needs 8 intermediates — Hardsilver Ingot ×2, Dragon Leather ×1, Hallowed Chestnut Lumber ×1 and 5 others — which resolve to 10 distinct raw materials totalling 40 units, plus 54 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,447 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 27 Wind Crystal, 13 Fire Crystal, 9 Earth Crystal and 1 other kind.

The chain crosses five disciplines — Blacksmith to Lv 57, Alchemist to Lv 56, Carpenter to Lv 56, Goldsmith to Lv 56 and Leatherworker to Lv 56 — so no single class can finish it unaided.

9 of the 10 raw materials come out of the ground, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

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