I can't, it's too old. I kinda' need to stop posting to this thread so that it falls off front page. Or start a new post I guess.
The recipe for plain arrowheads, *in FMR* (there is no such recipe in vanilla) got fixed in 1.1 and is now scale scraps + hammer. I'm open to feedback on that recipe though. You probably don't really need to make arrowheads except at very low levels (after a while they're really easy to find in abundance on merchants), so what components are very easy to come by even at low levels? I only picked scale scraps because of the deconstruction recipes I've added that give you an easy way to get any kind of scrap, now.
