Pactmaker's Creasing Knife ★★

Taken all the way down to base materials, one Pactmaker's Creasing Knife is 2 crafting steps deep and needs 3 intermediates — Eblan Danburite ×3, Lunar Adamantite Ingot ×3 and Ophiotauros Leather ×1 — which resolve to 8 distinct raw materials totalling 44 units, plus 50 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,595 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 21 Fire Cluster, 12 Earth Cluster, 9 Wind Cluster and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 90, Goldsmith to Lv 90 and Leatherworker to Lv 88 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Lunar Adamantite Ore (2:00, 14:00) and Raw Eblan Danburite (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Ophiotauros Leather has the widest use: 153 recipes call for it, spanning seven of the eight crafting classes.
