Diving Knife Single Edge

The knife I got was NOT the one pictured. But I like it better. It's double edged like a dagger and very sharp. What I don't like is the hard plastic sheath and the button to release the knife stays down. So to put the knife back in you basically need two hands. Would be better if it work like a holster so you could just push it in and it locks.

Well this was exactly as shown. Its pretty awesome. Its very sharp right out of the box and designed for ruggedness. I'm satisfied overall. Thank you...
