Wotan, great looking knife, you never cease to amaze me with your collection, have you thought that it might not be a makers mark at all, possibly just a design on the blade, if it is such a knife made by an apprentice then maybe he just added it to show what he can do, the position of it on the blade may be just a coincidence.I would be very surprised if he was allowed to put his own mark on it. Whatever it is, it takes away nothing from such a super knife.
