I'd go for all of them, depending on which race and/or personality I'd have in the universe these weapons exist. My favorite is the golden ceremonial dagger (because of it's looks, but it would require a lot of practice to use the curved blade effectivly) and #3, the stone/mace "hybrid".
I reckon one could find that deep in an overwrown Mayan/Inca-like temple :)
I have a question, though: What's an "aberration"? An evil creature? Golem? Skeletal demon?
