This is the perfect little knife to have. It is extremely sharp. It is very easy to open with one hand, and is very light weight to carry in a pocket, and the little clip on the side is quite useful. I have one with a straight blade and one with the serrated blade, which I carry clipped to my pistol holster in my car, and it will cut through seat belt material or just about any other material, if you should have to use it for that, or free yourself from a seat belt if you were unable to release the belt. As a self defense knife, it will either stab or cut, and is very easy to hold on to. As I said above, it is very light, and can even be clipped inside your shirt pocket and will not weigh the pocket down. Great little knife.
