Anyhow here's an edit I did trying to get some more contrast and lighting out of the lines and smoothing them out. I hope it is of some help.
Nice edit Delgneith!
IN general, this peice lacks the metallic properties of...metal
Up the contrast, and have a white hgihlight, as shown with Del's edit. Also, if you intended the lighter purple to be an razor edge, I would go for white, or near white, with greys shaded in with it..l did an edit to show some things I was talking about..
I messed with colors, and added a quick razor-type edge, it's not perfect, but it's alright for reference I suppose. Also, disregard the white spots on the handle..I was jsut messing around
