Maurice Johnson had two machines, with one having a looser stitch pattern. You see some of his from the early 60's with the loose pattern. I don' know if it was the same machine he used in the 80's, but I am going to guess not, but who knows. The main machine he used to make the "tight stitch" pattern did break on occasion, and he used the spare while his main one was being repaired. So it is not impossible to have a looser stitch on what we might consider an earlier appearing knife like this one, but it is not common.

In any case, I went and looked at the sheaths that go with the few examples 5" bladesI have, and Capt. is correct. In my haste, I seem to have put it with the wrong sheath. I will have to rephotograph it and repost.
