That is a very nice piece. A word of warning about reetching. Traditional etchants can and do initiate corrosion, which is why it is unacceptable in the museum world. I have, however, developed a museum acceptable method that is noninterventive (conservator term). However, the pattern will not be as visable as traditional etching, but the reflectiveness of the blade is better and the substance used is often used for the conservation of archaeological iron. What ever you decide to do, be careful.
