The blade of this knife is a sandwich of spring steel, solid along the cutting edge, with a center composed of two oppositely-oriented piezoelectric-fiber laminate strips. Buttons on each side of the knife's handle send a current to the piezoelectrics, causing the knifeblade to bend in the indicated direction. Pressing the right and left buttons simultaneously makes the piezo elements work against each other and provides a straight, rigid blade.-- Dog Ed, Jun 28 2001 $695 Bendable Fork www.hanklee.net/hankievision/index.htmlTo go with your $2000 knife.

[quarterbaker, Jan 25 2002, last modified Oct 05 2004] Global Flexible Fillet Knife http://www.cutlerya...etails.asp?SKU=1096Not $2000, but not cheap either. [bristolz, Jan 25 2002, last modified Oct 05 2004] Always wanted one....never tried to work out the details.-- reensure, Jun 28 2001 Yes! With a little tinkering, could it be set to wiggle about independently?-- The Military, Jul 04 2001 Can't see how this improves things over my 'normally' flexible carving knife, which bends which way I want by simply applying some sideways pressure. Am I missing something?-- goff, Jul 04 2001 Indeed! The potential for independent wiggling! Think, man!-- The Military, Jul 04 2001 goff: But does your regular carving knife cost $2000 US? And does it use elaborate cutting edge (!) technology in a completely unnecessary way? Well, *this* knife does. (Price may vary, check local stores if you have money to burn.)-- Dog Ed, Jul 05 2001 Why not just uses a boning knife, the tool butchers have been using for hundreds of years?-- mcscotland, Jan 25 2002 I'm with mcscotland on this one. Try a Global fillet/boning knife. Flexibility is controllable by resting a finger on the base of the blade. You can get the blade to follow the contours of the bone closely, especially when filleting fishies. True, it's not particularly hi-tech, nor is it $2K.
