I ran into this wakizashi which at first seems to be made from a yari, but it absolutely was not, it was made sort of like a steel I beam with 3 edges and was made to be non-lethal with all edges being made flat and the tip is non piercing also. I have a good idea what its purpose was but I wanted to see if anyone else had the same idea or some different theory. 



I will post the link again, the blade is close to some European blades except that all the edges are flat, it looks like it was never meant to be sharp. I saw a fencing blade that looked close. http://s831.photobucket.com/albums/zz238/estcrh/Triangle%20blade%20sword/
Uwe, I knew the image reminded me of something and I agree I have several socket bayonets and the design matches. Makes me curious about the age of this item?
