What hamon are associated with oil quenched gunto?

[Brian]

I know this seems like an elementary question, but I was wondering if there was a set pattern when it comes to arsenal oil quenched gunto hamon.

In other words, I know that we often see pure nioi sanbonsugi or suguha hamon that are oil quenched, but what about hamon such as pure choji?

Do you encounter choji hamon in oil quenched blades, or would this make you look further at it being one of the various Gendaito?

What about other more compex hamon?

yes, the oil quenched indicators are usually elsewhere such as pure nioi without hataraki and no hada, but was wodering how much the hamon pattern itself can tell about the quality of a Gunto.

 

The query stems from looking at a gunto such as the following one:

Given only thise photo criteria, would you still suspect possible oil quenching, or would you be looking to rule that out?

think you can rule out showato but it looks like a Emura or Nagamitsu to me, can you see a nice hada? Nei?

[Brian]

This one is an auction piece, and there is no hada or nie visible in the limited photos. Totally mumei nakago too.

I was just looking at it and wondering what are the odds it is oil or water quenched from this photo. With some Gendaito being made from non-traditional steels and some being semi forged etc, the line between traditional and non-traditional really is a close one when it comes to wartime blades.

Is it in gunto mounts? From the look of the temper its certainly not completely machine made and probably water tempered.

 

I agree with Stephen looks a lot like an Emura/Nagamitsu.
