Antique Tamahagane razor work in progress
This one is the 2nd razor I am making from the 16th century sword.
This piece came from a lower part of the sword, so it was a bit wider, allowing for an easier grind. And of course, the fact that I have worked with this material before helps. Grinding differentially hardened steel is a challenge. It is very similar to grinding suminagashi, so that helped as well. It is pretty jumpy on the grinding wheel. Only difference is suminagashi is easily replaceable, and this isn't.
First I cut the correct part from the sword.

Rough outline of the razor. No detail yet, just the outer shape
During grinding, the hamon came out. This is also where grinding became a true challenge.
This is with the hollows ground to final shape.
And this is without lighting, but with the areas marked that I want to grind down. The spine has to be made less wide. And I have noted where I would make a thumbnotch. I can also make a shallow fingernotch on top of the tang, between the tang and the spine. But that has yet to be confirmed.
Til shade is gone, til water is gone, Into the shadow with teeth bared, screaming defiance with the last breath.

This weekend I finished the razor. I mirror finished the body of the razor, and left the hollows at 120 grit satin finish. this way the hamon is really visible when held in natural light. The finer the finish, the harder it is to see. The scales are wild Japanese Cherry wood, with CA coatings inside and out to protect it against moisture. The wedge is made from ebony.
I really dig this model of razor.
Without etching or natural light, hamon on razors are notoriously hard to make pictures of. You can see a better hamon pic higher up in this thread.

Wow that is pretty cool! Who was the smith of that katana? Also somewhat a shame the blade hasn't been polished to see the hada, nioi/nie.
