I saw a factory recall on these at Bass Pro in Springfield, MO, the other day. If you will look at the corners of the deployment cam that is exposed during flight you will know if they are any good. The factory said if the corners are rounded the blades will not deploy on contact, but if they are pointed that's what you want. I looked at all of Bass Pro's 2 blade's while in the package and they were all pointed, I'm sure they went through them, too. Three blade was sold out or they took them all off the shelf.
