Hello JDW,
Very nice kitchen knife. It looks very comfortable and efficient.
This is the knife I am talking about:

I got the blade blank in the US and the knife was put together by a local amateur craftsman (he fixes outboard motors for a living) using a stag's antler that was hunted by a friend who also gave me the skin on which I took the pictures.
The idea is to enhance the pattern using some acid? or a rust blueing solution that will react differently on the steels used (I do not know what they are).
Can this be done?
JC
