Ive picked up two early Buck 110 knives in the last couple of months, and Im curious about the bottom of the two. I believe its an earlier model than the one on the top, and it came in a pouch that didnt have any rivets and has the 110 above the belt loop. In comparing the two Bucks, the lower one is overall thinner, has two different colored scales, the U.S.A. is smaller, and the rivets in the bolsters are not visible. Particularly noticeable is the single seam between the rear bolsters (third version?), as opposed to the double seam in the upper Buck (indicating a spacer between the rear bolsters-fourth version?). So do I have both the third and fourth versions, and which variations would they be? Thanks in advance for help.
