I am a police commander with 29 years service. I've collected and carried knives since 1969. The Puma Emperor in the old days to Darrel Ralph's Aftermath five years ago. The very best I've found is the Emerson Super Karambit with the wave feature. Its lightning out of the pocket, comes absolutely razor sharp and with the ring you can grip the knife and not worry about your hand slipping forward or the knife being taken away. My collection has 86 knives. I carry 2. The Karambit and a Spyderco Spydercard.
