Making An Athame Options

I've a question, wondering about the materials to use for making my own athame. I've obtained several arrowheads traveling and they spurred me to think of using them as the tip of an athame. Am pretty certain to make the handle wood, carved willow most likely, and bind the arrowhead with leather, died black. I am wondering though, if using an arrowhead would perhaps be an unwise choice for an athame, because of it's likely violent history? It could be cleansed of course, but thought to see what more experienced workers and magicians would recommend or advise. Am only beginning to delve deeper into my own craft practice (IMG:style_emoticons/default/smile.gif)~

More ancient customs involve digging a trench with a dagger and spilling sacrificial blood into it, and authorities on oriental mysteries identify the tool as a blood-drawing weapon specifically.

Hey there~ What precisely does 'oriental mysteries' refer to? Or what eastern paradigm is this a reference to? Or if it isn't a reference to sino/japanese culture, what does it refer to?
