I don't make them but that bevel is what they call a "scandi" bevel I believe. Not sure what the purpose is other than maybe they always done it that way? I would guess like a top false edge or bevel on a hunting knife which as far as I know serves no purpose. I do know of several knife makers that do bushcrafts with out the scandi grind on them. Here is an explanation from a knife website.
"Scandi
The scandi grind is about as simple as there is to understand. In the world of primary and secondary grinds, things and terminology can get confusing real quick. A scandi grind is simple, because there is only one grind, and you are looking at it. It is typically in the range of 12.5 degrees per side, or 25 degrees inclusive. With this being the only grind on the blade, the bevel created is wide and flat.
This grind is typically recommended for beginning bushcrafters because the width of the grind makes it very easy to sharpen. Other thinner grinds can make it harder to determine what the proper sharpening angle is. With the scandi grind, being wide, you can just lay it down, pivot the knife on to the grind, and it becomes obvious that you are holding it at the correct sharpening angle.
This is just my opinion that will continue to pop up multiple places on this site; if you don’t know how to sharpen your knife you have no business using it or carrying it. If you are out in the woods with a dull compound bevel knife and do not have the knowledge to do anything about it, you are in trouble. That is the reason the scandi grind is usually so highly recommended."
That being said by this fellow...I don't think the blades I get are "true" scandi grinds since they have a secondary bevel at the edge. Maybe someone with more knowledge can help.
