I just saw some crazy bastard (I won't mention his screenname) post on multiple boards. He is hawking a CHEST CRUSH certification using a CoC gripper and his "Rube Goldberg" handgripper helper device. Evidently you chest crush the gripper then hold it shut on camera. I guess you need to do what you need to do, to feed your ego. ;)
Think I'm kidding, read his web page HERE.
Tomorrow I will video tape me closing a #4 by stepping on it. I'm putting Ironmind on notice.
