I just forged this one last week , I posted a few pics ... After using Sen ( cutting tool) to smooth out profile
Finished it up with light grinding with 220 grit . Its ready for claying and quenching . Steel is 9260 .
similar to 5160 but less chromium and more silicon . Makes for a much more flexable blade, in my Opinion .

Still quite a bit of hand work , filing to get out the wavy portions from forging ...

Will post pics during quench and after ...... Bubba

Mind if I ask what your quenching medium will be? The reason I'm curious is because there is quite a bit of sori in that tanto as is. I've heard that water quenching will add positive sori to a blade (curve up), but oil quenching induces negative sori (curve down). Well, after paying better attention, you're using 9260 steel so probably an oil quench. So you forge in extra sori, because the oil quench will reduce it somewhat. Am I on the right track? I love Japanese blades, and I LOVE your work!!!
 
You are right on ... I am using oil quench . It reduced some of the sori . It looks pretty normal at this point .
