Hybrid Stone Polishing
 
This method is a little more expensive than a typical hybrid polish, but finishing it off using hazuya and jizyua Japanese finger stones produces a more natural nihonto style hamon.

   
Here is a Dynasty Forge Hybrid polished katana.
The hamon is not acid enhanced, so it is usually faint.
Here it is after my hybrid fingerstone polish. A very big difference.
It brightens the hada and makes the hamon whiter and more solidified.
Not even close to a traditional polish, but very good for a production blade,
Here is the hamon outside the harsh sun light. Very dramatic.
I've also done this to a forge folded Kogarasu maru katana.
Since it had a suguha hamon, it was easier to follow with the hazuya polish.
Here is the first blade I have fully repolished with this method.
It more closely follows the actual hamon pattern.
Here's the O-Katana in natural light.
Natural and artificial light can make the same blade look completely different.
Here's the hamon in direct light.
It's much easier to see the details instead of the overlaying white pattern.
Achieving a good contrast between hada and hamon is my goal.
I'd like to think I do a fairly good job of that.
Here's a shot in sort of low light. The hamon remains visible.
I also polished the kissaki to get a little more activity out of it.
It looks much nicer than before.
