I've never understood for a while why SE doesn't just combine the looks together for a truly unique weapon (Long sword with scythe shape on end). Here's some interesting pics from google:





I guess the fact that a majority of all our swords are nice and straight is part of the problem? Well, shinryu's greatsword atleast has a second blade on the side. They could at the very least get more creative with our sword shapes without a need for a scythe.
