Alumina Whetstone ★★

Nothing in this list is craftable in turn, so one Alumina Whetstone is a single step: 5 units of material drawn from 3 base items, plus 4 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 564 of the 2,216 Goldsmith ones, and 9,374 recipes nest deeper.

1 of the 3 raw materials come out of the ground, and one of them is time-gated: Beryllium Ore (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Alumina Whetstone is itself consumed by 51 further recipes, spanning four of the eight crafting classes.
