This is a long lasting and dedicated mostly Case xx knife club, as 22 Case xx knife variations have currently been documented on KnifeDB.com.  The first club year was 1989 and the last knife documented so far is from 2018.  This club consistently made beautiful knives in very limited quantities.  The smallest run seen only had 20 variations, most had 50 or less.  Several of the club knives came with COA’s which is unusual.  They also did another unusual thing:  they would make an annual club knife, but only half the run would have the unique club blade work.  The other half would have a plain blade, but could still be identified with this club by the unique circle C shield.  (See the knife pictures).  The club also had consistent designs on its special features.  (See the blades below).   Here are some Circle C goodies.
