Some buyers other Damask knife from this manufacturing fault, or say it is not a Damask steel or iron. I have the blade totally durchgescheckt, with Microscope and files, etc., the details of the company. Asaz on the steel / iron, on the layers, are absolutely correct. Here is a fake to seek more than amateurish. At first glance, and with your fingernail to spührt the genuine damask knife. Especially after a detailed technical examination. All Damask steels are etched to have the grain appear.
Fake damasks, visually etched are, indeed to have on the market, but here definitely genuine damask.
The blade is slightly rust for the used steel / iron product completely normal. A samurei had to take good care of his blades.
