The orientation on the No.8 and No.9 aluminum snaths is correct, but the orientation on the No.1 wooden snath has been about 20° or so out of alignment for well over a decade, probably closer to 25 years at this point. Sometime around the early 90's by my best guess, the collar started getting installed so that, when held with the collar square with the ground, the arch of the snath bowed out
towards the user. This gives zero advantages whatsoever, and causes the arch to strike the thighs and knees during the stroke. The one I received over a year ago that I ended up giving to my father had this problem, and I had to adjust the roll of the tang (as in pitch/yaw/roll) to compensate for it, which then skews hafting angle adjustment.
This was the video I had sent them to illustrate the problem, along with a relatively recent vintage No.1 snath (most likely from the 80's) that had correct orientation, like all No.1 snaths did up until then.

No American snath manufacturer in history, including Seymour, has ever purposefully produced a snath with the arch facing the user. Their aluminum snaths are still properly oriented. Why they would choose to keep the collar incorrectly oriented is really beyond me. I was hoping to get them fixed so that every current retailer of the No.1 snath would have them properly oriented, but I guess I'm getting the rare distinction of being the only retailer to have them put together right.

My thanks to their VP engineer for at least being gracious enough to make the components available to me.
