Also at this blade my friend has worked and has done a very good job! I wasn't happy with badly grinded tip of the blade which now look good again. The blade has get also a polish and etch and shows a subtle lamination. Interestingly there are visible on both sides of the blade two finger prints after etching. My friend told me that he has seen them after etching and has polished this places again but after etching they has been visible again!
He think that it could be that a previous owner has touched the blade with bloody fingers. Here some pictures.
