Exactly what I brought up in the third paragraph of my first post. I myself found the transition from the 'crude' to 'decent' stage way too quick for my taste. I say, a few hours and you already got yourself means to play with iron. Like there are no more fun materials to exploit. Take bone, for example. There are so many bones one can find in a skeleton, other than these of a skull and collarbones, They were also put to many uses other than being hung as trophies or kept for good luck. I don't see why wouldn't a bone make for a nice spear tip or a needle (even if not as well as their iron counterparts).
As for armor, at a primitive stage you could make some from wood (like [url=http://www.amnh.org/var/ezflow_site/storage/images/media/amnh/images/exhibitions/permanent-exhibitions/human-origins-and-culture-halls/hall-of-northwest-coast-indians2/ts_8.8_woodenarmor.jpg/1502904-1-eng-US/ts_8.8_woodenarmor.jpg_imagelarge.jpg]that one[/url], for example). The first type that came to my mind was hide, though. I even thought of its specifics: weaker, heftier than leather armor and more prone to decay, but its creation would not require the hide used to be particularly prepared. As such, it could be made more easily and with limited access to tools.
Weapons? Well, as I said before, Wurm offers quite a selection of stuff that could be swung at stuff, but for some reason forbids us from doing so. And there are so many wooden weapons other than staff and clubs, the latter of which seem to be too complex for a human to craft - only Trolls, having conducted lenghty and rigorous scientific experiments, came to a conclusion that giving a hefty piece of wood shape and swinging it, like, very hard at a target is a viable combat technique. If Humans find their clubs too heavy or taking too much wood to craft, they could make lighter clubs of their own, right? Maybe strap a stone or bone as well, for that extra "oomph" factor!
Well, there's always a crude axe: http://www.wurmpedia.com/index.php/Crude_axe
Too bad it performs poorly on local wildlife, though.
