Here is the second round, photos courtesy of Ron Mathews. This photo shows Heiser, HKL, and Johnson. L to R Johnson - Johnson - HKL - Johnson - Johnson - Heiser.

Note that two of the Johnson made sheaths have center keeper snap location and are brown buttons, contrary to the "theory" of the opposing camp.

With rear of sheaths photo added, again the differences between Heiser/HKL and Johnson are clear. Stitching, butterfly, belt loop width. Notice also that the two Johnson made sheaths to the left have west facing logo stamps and serif numbers designating model/length, again contrary to the opposing camp. Note the two Johnson to right are without model/length stamps and have edge keeper snap location.

Ron's own assessment:



I agree except I think third from left is HKL
