I bought the jump knife, because I suffer from insomnia after two strokes, and I therefore often late in the evening or even at night again going around the block to get tired. There are a some security from wild animals or the like. The blade fits nicely in your pocket, the blade can be by simple keystroke extend and has a lifting device. The processing also makes a good impression. There nothing wobbles and the blades export responds quickly. The only drawback: There are some rivets on the handle, which protrude slightly and could eventually damage the inseam pocket. I would buy the knife still again.
