I have quite a few comments on this:
-To me, it looks like you just rotated the whole thing in mspaint or something. The middle frame has random pixels coming off of the crosspiece, as well as having a horribly jagged outline.
-I'll agree with earlier comments about awkward hilt motion, strange shading shifting, etc.
-The shading doesn't really make sense, either. What kind of lightsource would cause that kind of gradiential shading across a flat surface? I'm aware that that's how stereotypical sword shading is done, but just because it's stereotypical doesn't mean it's right.
-I would recommend losing the internal black outlines. The crosspiece is only three pixels thick, and two of them are outline. Surely there's a better use for those pixels?
-This blade does not look all that sharp, and certainly not sharp enough to cut through "wood, rock, and anything". In fact, the blade this most reminds me of is a butter knife. Perhaps it's the blade shape, but that's what sprung to mind when I saw this.
Overall, I can't think of much good to say about this. It looks like a rushed job that needs a lot of work. Frankly, I think you might be best off starting over if you are trying to make a sword that is as sharp and cool as the described sword is.
P.S. What does this have to do with the word "disc"? I see nothing disc-like in the design, and would like to be enlightened as to the source of this name.
