I am all for the hardhat and the sledgehammer if it improves team cohesion and morale. But has anybody actually seen a real jambar. I can't find a picture. I know it was a steel mill tool and used to pry components that were stuck. If it turns out that the jambar looked vicious and menacing, would that not make a perfect item for this team-building exercise? Unique with deep meaning to this former steel community. Better than the generic sledgehammer that many colleges use. We could probably make one via additive manufacturing.
Of course, if the jambar was small and anything but vicious in appearance, this would be stupid idea.
