What the allowance actually buys
One allowance here buys 21,830 EXP, which places it 5th of the 6 Lv 25 Blacksmith tradecraft leves that record EXP — a figure 1 other leve on the rung matches exactly. The best of them, Lancers' Creed, returns 47,200 EXP for the same allowance, 116% more.
Across that rung the return runs from 21,830 EXP to 47,200 EXP per allowance — 4 distinct figures spanning 116%, so the wrong pick leaves 25,370 EXP of the allowance unspent.
On whether to wait: the best Lv 30 Blacksmith tradecraft leve returns 67,730 EXP per allowance, 43% more than the best on this rung, while the Lv 20 rung behind tops out at 21,600 EXP.
At Lv 25 this data holds 52 leves paying EXP across 2 categories: the 48 Tradecraft ones average 31,772 EXP per allowance, the 4 Fieldcraft ones 204,269 EXP, which puts this leve 31% below its own category's average.
Gil ranks it differently: 114 gil per allowance is 6th of 6 on the same rung against 5th on EXP, with the best there paying 534 gil.
Iron Round Knife ×1 is a Lv 25 Blacksmith recipe, 2 steps deep through 3 intermediates, costing 8 units of raw material and 8 crystals.
Handing that in returns 2,729 EXP and 14 gil for every unit of raw material the order swallows, and the tree needs Blacksmith, Carpenter and Goldsmith.
