Another new one just in. Real Green micarta scaled SPRING assist knife. Double sided thumb stud and an index finger flipper stud. Nice thick handled knife. Satin finish all around. Partially serrated blade measures 3-1/4". Liner release to close the blade. These new torsion assist knives are the biggest rage. With just a slight flick or nudge on the thumb stud, your opened up in a fraction of a second.
