Cobalt Culinary Knife

Taken all the way down to base materials, one Cobalt Culinary Knife is 2 crafting steps deep and needs 3 intermediates — Basilisk Whetstone ×1, Cobalt Ingot ×1 and Rosewood Lumber ×1 — which resolve to 4 distinct raw materials totalling 7 units, plus 26 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 507 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 11 Wind Shard, 10 Fire Shard and 5 Earth Shard.

The chain crosses three disciplines — Blacksmith to Lv 44, Carpenter to Lv 45 and Goldsmith to Lv 40 — so no single class can finish it unaided.

One intermediate outranks the result: Rosewood Lumber is a Lv 45 Carpenter recipe feeding a Lv 44 craft, so that step, not the last one, is the real gate.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.
