Has anyone seen or made a mod that makes the thrown weapons in fallout new vegas recoverable, such as the throwing spear, throwing knife, and throwing hatchet? If not how hard would it be to make?

I'd like to know the same thing

My 3rd character is going to be a former tribal, so I hope to use throwing spears and axes extensively, but if they just take up weight and can't be reused I won't be able to.

Arrows could be reusable way back in Oblivion, with the same engine, so it seems like it should be possible to mod in.

I agree, a possible recovery chance would be nice.

Maybe this is what you had in mind: http://www.newvegasnexus.com/downloads/file.php?id=35101

started a thread on it too and that's the mod in answer. also here's the thread http://www.gamesas.com/index.php?/topic/1127843-improved-throwing/
