Laser etch, out of Europe, 205.00 a piece, steel is less hard (under a 56 RC), laser lateral lines present, , there are no nibbles at the outer or inner edged of the etch, too clean. maker never made SS (as of yet unseen), If you take two original blades and strike them (lightly dang it!) they will ting, fakes from Europe kinda thud. They are all over Ebay, and have arrived at Gun..... as well. The angle (4 degrees) is also off on these blades at the shoulder, they do not fit crossguards well (too much or not enough arch in the blade shoulder or crossguards).
Just my 2 cents.
