Jim, I own many old framing chisels and slicks, from my sampling, cross pinning has not shown itself and I believe for good reason. It is in the nature of metal sockets and wood handles to advance deeper into the socket through use by progressive cell collapse by compression in the wood fiber. The two mechanical means of compression are moisture cycling and the pounding. It is best to let the progressive micro-reseating take place unabated and not have the rivet or screw as a point of failure.
