First of all, why does the kunai have to be crafted? Heck, the items to "craft" them are sold by two NPCs directly next to the NPC that actually makes the kunai. It would make a heck of a lot of more sense if you could buy them straight off a vendor.
Secondly, would it be possible to put a kunai salesman somewhere in Prontera? Preferably near a kafra? Throwing Ninjas go through their kunai quickly and it's really annoying to have to go all the way to Amatsu to stock up everytime.
On top of that, the kunai are very heavy, so you'll end up having to make 3 or 4 trips between the Kafra storage and the kunai crafter to stock up for a day or two of leveling.
