FYI, there is a copy of "How To Make MULTI-BLADE FOLDING KNIVES" by Eugene Shadley & Terry Davis, with foreword by Tony Bose, up on ebay right now - item #220191015009. I know a number of you have been looking for a copy of this book, and they've been pretty thin on the ground recently. (Disclaimer: I've got no association with the seller and have never dealt with them. YMMV)

yep...that is a nice book to have

Thanks for bring it to our attention.

FWIW Ive seen these books go for well over a hundred bux a pop
I spoke to Gene awhile back they may be planning another edition perhaps even updated.
