The Steel Tiger is sort-of abnormally large for a karambit. Came razor sharp out-of box. The tip appear delicate but during one of my fooling around session, it slip my grip and flew, tip-first into the composite wall of my room, no damage to the blade upon inspection but that's the last time I fool around with a karambit. Imagine if someone else happens to be in the vicinity... Unless you are trained to use one, I would suggest a conventional fixed blade/folder as a self-defense tool. CS Kobun or the Spikes series are great featherweight fixed blade.
