Greetings all. I'm a new member, and I'm very happy to find your forum. I hope i don't need to pay for a membership to post but here goes ... I'm interested in getting my first knife for self-defense. The sentinel gear MK3 looked very appealing. But before I make a purchase, I would like to get opinions from the members here. Are there other quality knives that are more affordable? I would appreciate any suggestions.
