Artisan tools are just 3 star synths, the only difficulty is the 6 sealant can't be HQ. If you get the other items HQ you start with about 700 Quality.

The books are one of the other bottlenecks, mostly for the fieldcraft III. If you don't have leather desynth, you might as well just buy them off the market or have a friend that does and offer to buy in bulk off him. I desynthed 100 boots the other day, got over 30 FCIII for 600k, plus half a stack of wool cloth and some hard hippo leather.

Another bottleneck is the materia to meld onto them, it really starts to add up when you need to overmeld at least 2 tier III materia per tool. Another is the mastercraft if you still need to get supras. You can get mastercraft from forager hats if you have weaver desynth leveled, but it's a slower pace than making tomato relish for hours on end.
