(whoops, I didn't realize there were responses here . . .)
For the Buster Sword, sure the handle needs to be offset a bit, but to the other side. On the cutting edge, the sword is much thinner, and hence, much lighter than on the backbone side. The Buster's hanle should be towards the backside of the blade, just like how, for example on a katana, the handle is "curved" in the direction of the backside of the blade.
I think you're right. Functionally, and as with any sword weapon, balance is key, and having the hilt offset like I have it now would make it very difficult to use it.The hilt should be horizontally centered with the swords center of gravity, when in an upright position.
@ Corsair: Critique.
The more brutal the better, friend! Really, your post was just fine.
True we're rationalizing against an impossible sword design, but it's good for it to not be distractingly built. Regardless of the perception of the 3 people who will see it. Once I begin work on the buster I'll address it's wonkyness.
Colors. Sorry for not being clear - that first WIP state has all 3 swords created, but just basic shapes, randomly color-coded so the different parts can be differentiated between when it comes time to pixel over. Auto AA heaven. The 9 colors thing means I will eventually reduce it down to only 9 colors, I just don't know which yet. EGA palette is chosen, though.
UPDATE: Claymore hurredly began - Default EGA colors only now, looking slightly more visually interesting, but still quite poor.

(looks like it may be wise to reduce my templates size, next time)
