I too was looking for a set of Chuppa knives. I bought this one knife, back in 1980 at a grocery store, and its still sharp! No rust or anything!   

Did many searches, many times, and finally got a number in TN, called it, and it'd been changed to a number in Florence AL.

For the guest that posted looking for Chuppa knives, the phone number is 256-767-5119. They are in Florence AL, USA.

They are going to send me a catalogue. Seems their webisite isn't up yet. No wonder I couldn't find didly about them on the net!
