I'm speculating here, just a vision that came to me...
I'm thinking CRK may launch a European-manufactured and imported line of knives, perhaps made in Italy (perhaps by Fantoni, who made the recent Chris Reeve/Harsey collaboration), and wants the "Idaho Made" stamp to readily differentiate his 100% USA-manufactured pieces.
Besides that, and to answer your question, I like the stamp and the pride of every man and woman in the CRK shop it signifies. Not saying anyone who doesn't like the stamp doesn't appreciate the pride, just sayin'.
The stamp's ok with me, though I might have a few older CRK's to wear out before I have to worry with picking up a new one anyway.
