I have had my eye on the Benchmade OTF "Out The Front" double action Infidel since they came out. I decided to go with the utility serreated blade instead of the double edge version. When the knife button is pushed forward the knife slams open with surprising power. With the knife fully open there is no slop between the handle and blade. This is a common problem with double action OTF's. Benchmade eliminated the problem with supperior machining when fabricating this knife. To slide the knife back into the handle you press the button in the opposite direction of opening it. Very crisp and durable knife. I find myself in front of the T.V. opening and closing the knife just for fun. It is addicting trust me. The blade is unbelievably easy to sharpen and holds an edge for a long time. I have had several benchmade knives over the years and many other brands as well. This knife is now my go to knife and I keep it on me most all times. I don't know if they are legal to own in O.K. but they are legal to own and carry here in Oregon. I would recomend this knife to any one looking for an automatic knife.
