Hey'ya... My Hanwei Tiger katana got into serious rust problem lately, causing some slight but ugly pittings on the blade Some of these rust were on the kissaki area and, in my overly zealousness to polish the rust off (using Autosol), I inevitebly rubbed on the 'greyish' hamon surface and now it's hardly visible All along I thought the Hanwei Tiger katana was true differentially hardened and the hamon should Not be 'erase' off like this?!! Is anyone familiar with this Hanwei kind of hamon 'etch'? And, can anyone advise how I may put the 'greyish' hamon back as best as possible?? Any advise will be greatly appreciated. Thanks in advance

Sounds like it was acid etched. Its the real hamon is still there, its just that acid etching it brings the hamon out even more. However, you can "erase" the etch with mild abrasives. You can re-etch it with a diluted ferric chloride solution or a white vinegar solution.

Larry, you might try PMing Slavia631. I'm fairly certain he posted a hamon etching tutorial or at least some tips on it.

Ive just finished one blade and its turned out fantastic. it was a cheap chinese unbranded katana with rubbish fittings and i had nothing to loose if i muffed it up. It had a nice hamon before and this process just made it better.
Ive also just started on a hanwei ppek last nice and went through the process once. The results arent as good so im going to do it a few more times on my day off tomorrow. Ive got pictures of the entire process and ill post them here when im done.
Does repeating the process bring the hamon out more each time or am i just wasting time? Will i see a improved result if i repeat this ten times? I haven't seen any pictures of the results of a vinegar polish on hanwei practical line blades.

UPDATE: Did the vinegar etch once more and VERY gently polished the blade back with metal polish thinned right down with 3in1 oil. Much better this time.I can definatly see more going on in the hamon. I need to counter polish the yokote. Ill take some pictures tomorrow morning as the light inside is rubbish.

I carefully taped my Hanwei PK and went through the entire hybrid polish method (had to tape and pack around the habaki with dielectric grease since it does not dis-assemble). I tried several times with different mixes of the etching material, but for the first time in trying this method, I could not get a hamon to pop out. I only succeeded in making the blade really shiny (and amazingly sharp..... I mean nightmare sharp!) Is it possible the PK is not truly DH or should I try something else?
