Interesting reactions based on what people think it is supposed to look like.
FYI, the UC blade is exactly proportional to the handle, and exactly matches the patterns of the film scale Weta prop I used to create the 2D and 3D CAD used to build it. And the larger actor scale prop matches the film scale prop shape and proportions to the T, if anyone is wondering.
Side-by-side the UC and Weta are about 98% the same in shape. Regarding the grip being all wrong, the UC sword grip was actually created from a 3D laser scan of the prop. The shape and every detail is the same, even the bow to one side (it's not symmetrical). The coloring is pretty damn close too, although if you watch the film carefully you will see the grip is darker in some scenes and lighter in others. We were told this was happening on set as the grip was handled (the prop grip is painted hard rubber), but in general, the color in the film is consistent with the prop, and that is what we copied.
