I don't use blender so I cannot view it. The screenshot shows a lot of unnesesary polygons on the blade. You can do with a lot less!
Also, the shape's a bit wrong for a sword, I would say. Looks more like a dagger. Make the blade a whole lot longer and the handle just a bit to remove the 'fat' look of the model.
I do not use blender, but I agree with Sph!nx about the extra polygons. The sword reminds me somewhat of a hobbit sword or a cartoon one, if that is the look you are going for you are doing great!!
Over 3 years (has it been that long?) and just now I noticed the day and month of my birthday were switched. Whoops!
