BF Ultra FIE Blue Maraging Epee

I don't own one of these blades, I use a Leon Paul maraging blade that I'm very happy with, but two guys in my club use them. One is stiff just like described by the previous poster and is extremely painful to be hit by. The second is as flexible as you would want any blade to be. From what I hear these blades come in batches of varying quality and flexibility so you really should test out before you buy if at all possible.
