I had to Google this one and found this website for the Bernina 504 Wenger Swiss Army Knife:
http://www.wenger.ch/bernina-504-6-504-042-013 .
I didn't find the price at that site but saw:
http://www.craftbanter.com/showthread.php?t=60238 Bernina Wenger Swiss Army Knife for quilters - $110
Definitely an item that goes above and beyond the basics needed for quilting.
