Favorite Karmabit once it's opened
I run a program that teaches karambit as a self defense tool. I've owned/carried a number of folding karambits (which are always a compromise. Fixed blade karambits and knives in general are always preferable where legal). Besides the Emerson, Fox, and 511, this is of the the few folding karambits I would carry. Like all balisong knives, the opening of this one is "dainty" and not certain (less certain than a real balisong because the blade is not symmetrical). Once opened, however, the grip reinforces the lock-up and the three points of attachment of the blade make striking with the spine about as safe as it can be on a folding knife (the jimping and and pointed swedge seem to be made for this purpose). The cutting edge of the blade measure 1.75" which is really perfect for a reverse-grip close-in self-defense tool, and the rake on the blade is also perfect. The blade is very sharp, but as a steel is proprietary there is no evaluating it's quality - time will tell. The pocket clip is a folded-over affair, which means that screws protrude where it engages the pocket and abrade it a bit. Those with big hands will find the ring a bit on the small side. The "cool factor" of the knife is it's weakness. The dainty motions required to open the knife one-handed, while easy to perform on your sofa will be extremely difficult to execute if someone is choking the life out of you. You can deploy the blade more surely with the support hand, assuming you've got the use of both hands. Once the knife is opened, however, the size, rake of the blade, aggressive spine, and solid lock would make it the choice of karambits I own.
