After spending some time enjoying the amazing technicolor patina's that my Gesshin honyaki took, it eventually evened out into a stable, but uninteresting muttled dark grey.
SO, I decided that it was time to clean it up and test out some different methods for bringing back that sexy hamon.
Here's the patina at the pinacle of awesome:
...and after sandpaper, stones, mud, etching, polishing, re-etching, and lots more elbow grease:
It's certainly not "traditional" but after many hours over several days of experimentation it was the most even, detailed and dramatic display of the hamon I could manage.
I haven't cut anything with it yet, but I'll be curious to see if the patina develops as brighty over the etched steel (even though it has been highly polished an the oxide mostly removed).
So lets see what ya got! This is the most difficult, labor intensive finish I've done on any knife so far, I'm interesting to hear the process of how other folks finish honyakis and the results that they get.
