Lew,
If you have more of such passing thoughts, just sit in a corner and wait till they're gone
You had the comments of Rick, David and Alan. They said enough.
I know some Dutch fellow collectors who always start to look at the pesi. When the pesi is damaged or broken or even restored because the blade is so old and the pesi is gone, due the centuries of etching, they consider the whole piece as worthless. Reason for that is the esoteric side of keris Rick mentioned.
