I don't believe that is the case wally, depending on what we call a Zacharias fighter.

I know of two in existence, the original Zach and Tune's knife. I don't think Bo made more than a handful of this style as it was not practical for utilitarian use with the finger grips on "top" of the handle and the odd hilt.

I believe he moved to a more "traditional" style rather quickly and most definitely with the introduction of leather handles in November of 1942. All of the earliest knives other than the two mentioned that I know of are leather with finger grips. I believe he made the majority of the 28 knives during this period after the introduction of leather.

Brian's knife that was mentioned I believe was made in the latter part of 1942.
