Silver Head Knife

Taken all the way down to base materials, one Silver Head Knife is 3 crafting steps deep and needs 5 intermediates — Iron Head Knife ×1, Silver Ingot ×1, Mudstone Whetstone ×2 and 2 others — which resolve to 4 distinct raw materials totalling 13 units, plus 18 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 695 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 7 Fire Shard, 6 Wind Shard and 5 Earth Shard.

The chain crosses three disciplines — Blacksmith to Lv 30, Carpenter to Lv 25 and Goldsmith to Lv 23 — so no single class can finish it unaided.

All 4 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
