Cold Steel Mini Koga SD2

Of the two models this is hands down arguably the best if the pair. Much lighter and feels more natural in one's hand. Smaller and less obtrusive to view. 6 and a half inches long with half the weight of the larger model companion design. One inch thick so easy to hold onto whereas the thicker other model feels like it might need some way of securing to ones hand like with a cord tie on. This one is good to go however and wouldn't go flying out of the hand in demonstration use in training. Very highly useful non lethal method of striking to an attacker's pressure points. More a deterrence device than a self defence device proper some might claim. Books upon the subject are considered required reading in order to use any type of Kubotan effectively and usefully. I would advise. In use this proved still probably the most workable type design. To my opinion superior to wood or light plastic and especially safer in use than any metal type. I recommend this product without hesitation as the best one out there.
