Not sure if it is just not in yet or there is none, personally I hope there isn't one at all. I'd prefer to just gather recipes and experiment because frankly it was annoying in DoS 1, which I have yet to beat and want to.
I find you need to gimp one of your mains a tad to get the crafting without using too much crafting gear, or take Jahan and I don't really like Jahan, he's a bit of a dick.
For crafting recipes, I haven't really experimented too much with crafting, I tinkered with some potions to see what I could get but all I managed was a minor healing potion of which the healer on the beach teaches you for free if you just talk to her and want to learn, though you may need the [Scholar] tag, it was how I got the stuff.
Obviously Knife + Branch/Stick/Twig is probably Arrow Shafts along with any Arrow Shaft + special arrow head makes that one.
I'm unsure how or if we can break down other items like metal salvage I was hoping to break down into ore or bars or something that maybe I could make some armor or weapons out of, but I haven't discovered anything yet. There may be a forge somewhere in Fort Joy that I just missed and we can use an anvil/furnace there, no clue gotta explore it some more.
