Well, I finally got Arcanum to workin (actually I installed it on someone else's comp ), and I was wonderin what and where a good, non-magical throwing weapon is. And I don't mean like explosives you make. Lookin for stuff that isn't one time use only.
Bladed boomerangs, balanced boomerangs, and plain ol' boomerangs can be bought from smithies. Magickal throwing thingies work perfectly well with a techie too, unless you're avoiding them out of principal. Of course the Holy Grail is the Flying Yo-Yo of Doom, found at 750W 556S on the person of the Old Blind Master. It's neutral, and does huge damage even though its range isn't as great as, say, Azram's Star. (Throwing master quest.)
