Er, this type of sword looks like it can't do much damage, at all.
The blades design looks like its rather weak, so it could break easily, and the curve of the blade is unconventional. And lets not forget, it doesn't look like it can cut with anything other than the tip of the blade, the rest of the blade looks like it'd sink into and ensnare itself into flesh, making it difficult to cut through and pull out even due to the curve. But then again this is a weapon suggestions so..
