I have been wanting a nice flipper for the past few months now but I just don't know what to get. The two knives that I think of for a nice flippers are the Zero Tolerance 0560/0561 or the Microtech Whale-shark. There is also some photos of a Spyderco flipper called the Brad Southard Folder which is still a prototype. So the question I have is what is a good flipper? I am looking for something that is anywhere in the price range of 200-400 dollars and preferably American made knife.
