The way the crescent blades are arranged one gives up some extension if hands must stay in the blue-wrapped areas of the handle behind the crescents. By shifting the leading hand backward into the relatively unprotected middle area as shown above one increases the striking distance, at least temporarily. Perhaps a more continuous parallel second blade should replace the two crescents. That said, threading the needle to strike in the middle of the handle while the butterfly (or cicada) wing is flying is no easy task. The weapon as built seems ungainly were one to try to wield two at once. However, if it could unscrew or otherwise separate at the midpoint of the blue handle area one might have two formidable swords.
