Not my theory. The "tooled" edge I believe is a misnomer in that it is a byproduct of the sewing process. In other words, it is a result of the foot pressure as far as I know and possibly the shape of the foot itself. I don't know if you can set the pressure intentionally to get that type of result or not. Sometimes Johnson's will have a bit of the tooled edge and sometimes they won't, at least early on. Heiser almost always had it and it is more pronounced.

So what are you getting at? If it has any "tooled" edge at all it is a Heiser? If it has none it is a Johnson? The sheath on the far left in Ron's photo appears to have a slight edge but it is difficult to tell for sure in the photo. Ron could clarify that.

Tom, when you look at the five sheaths in Ron's photo, do any look like the Heiser to the right? Stitching, leather, overall finish? Anybody else? Whaddya say?
