I have a smaller knife of similar style and same materials. Mine is apparently a Kinsfolk, who marked their knives with only a blade etch that was easily worn off.
Perhaps yours is a Kinsfolk as well? Better pictures of the tang area and sheath decorations would be helpful. No offense, but it looks like you used a cell phone in less-than-ideal lighting conditions. If a cell phone camera is all you have, try laying the knife on a flat surface outside in the shade.
Best luck in your quest.
