Does a hamon degrade with repeated tempering?

    Ok Brad... I etched my knife and it looks like crap. Used hot vinegar. I also used 0000 steel wool to rub the oxides off. I realized after several cycles of etching an cleaning that the steel wool wasn't getting all the oxides off causin a splotchy etch. I am going to sand it down and try again. What do you use to get the oxides off?

    [​IMG][/URL][/IMG][​IMG][/URL][/IMG]Well, I can not say I didn't try to get a hamon. I am a little disappointed as I know I lost some activity but I am thankful that I have a blade I like that I will finish up. Thanks for the help Brad...here are your pics. Any thoughts on how I could improve upon developing the hamon would be great. In a different light I can see the ghosts of the ashi pattern I put on the blade.

    You will have to excuse the pics, I am not a professional and I don't have a light box.

    The activity still might be there. Just keep at the etch then polish you may see more. I use flitz to clean the oxides off my blades, NAPA liquid metal polish also works pretty good too.

    That is a real great looking knife by the way good job. Taking a picture of a hamon is tough

    Thanks Brad. I'll try another round of etching tonight. I used 3 vinegar and 1 lemon juice etch, cleaning off the oxides with Silvo. Then I scrubbed with windex and soap/water before etching again. 5 minute etches where I just keep applying the etchant. I also put dish soap in the etchant. I have some rottenstone I might try to see what happens when I polish it.

    This blade is many firsts for me. First hidden tang, first hamon, and it will be the first time I use antler for the handle. It is probably a little over my head but I'm taking my time. There have been many aspects to this blade that I have had to figure out. It's not going to be perfect and that drives me crazy!!! I hope my hunting buddy and good friend appreciate the effort as he is getting it for his birthday.

    [​IMG][/URL][/IMG][​IMG][/URL][/IMG I did more etching and polishing tonight. Lemon juice only. I think it made a little better definition and seemed to develop a bluish halo right above the hamon line within the whiter area. Unless I find a more interesting polish or some powdered abrasive, I will leave it here. What do you think? I am not sure if it is that noticeable in the photos but I can see the difference in hand.

    I actually found white vinegar worked much better that lemon juice. So maybe give it try a on your next one and see if you notice a difference.

    Looks awesome!

    Brad, stevenbates, and Alexander13

    Thank you for the compliments. I'm starting on the guard now. I have a feeling it will be a lesson in frustration. Not sure how this will look in the end. The antler is going to be a little difficult to work with without it looking really odd at the guard. I'll post when it's done.
