Thanks guys, I was also thinking of using it on a couple of fixed blade designs like neck knives. Though that would be limited as I generaly don't like thumb serations on anything but a light duty knife.
Peter I've been thinking along thouse lines(was thinking of turning one blade one way and the other the other for dept and spacing and silver soldering together) but haven't tried it yet, now I'm going to have to destroy a perfectly good hack saw blade!
I guess since the numbers are per inch I could draw it out and figure out what I need.
Thanks guys.
