The method Bernt Damm describes was demonstrated by John Grant at
a workshop during the 1992 MBSI National Convention in Washington D.C.
I recall that he separated the box with one well placed hammer blow
but I don't remember the details.

I don't know if John is a subscriber to MMD.  In the MBSI Directory
his e-mail address is listed as <rdawgie@mindspring.com>.
