Hers another recipe that I am adding:
At ~28 make Beetle Arrowheads. 1 beetle Jaw and 1 Bone chip, and 1 Wind Crystal. Very easy to make, gets your skill up fast^^
At ~32-33 make Fang Arrowheads (YAY) This is what I am on now, and I love it because while I'm waiting for a party I can pop out into Battalia Downs and farm Tigers (YAY).
I'll tell ya how it works out^^. Btw I havent seen this recipe on any of the recipe websites, dunno why.... so I don't know how far its gonna take me, but I plan on making Bone Knives at ~36-37
Good Luck
