The first & second sheaths (on the left) are identical, with regards to the stitch size and pattern,(in regards to the way the hone pockets are attached). The same can be said for #4 & #5. The Heiser is totally different from all others. Number 3 has aspirations of the Heiser look, even to the extended back-stitching atop the edge side of the hone pocket. #3 has a screwed-up sheath stamp also??
