Wasn't sure what the quality would be like but blown away by it. Big, heavy and solid, it's non-magnetic so I guess it's brass by the weight of it, and the hole for the finger is just big enough for my middle one to fit. The removable brass point is a good idea as in my experience they don't contribute enough to the pain to justify the risk of twisting your wrist by an awkward impact, and the main body is so utterly effective without it. One of these saved my bacon twice, once maybe really saved my life, and they are devastating. It's like a light switch, you don't need all your effort, just good aim anywhere along the jawline and they're out. Both times just *click* and it was over instantly. Great for self defence.
