Identifying Nie and nioi self study

[Paz]

Just doing some studying.

 

The below image represents nie, nioi and kinsuji ? Am I correct ? 

I'm not 100 percent about kinsuji part though thanks. 

 

Any tips will be helpful.

Mostly nie for me.

I see kazunoko nie and ashi

 

or juzu ba?

Thank you. I find it difficult to spot Ashi. On the description for this blade, ashi was mentioned.

Your pictures show the steel pattern well but i wont be sure if the "rough" parts are more influenced by the folding or the hardening.

You will need to adjust your angle to the light to see the effects of the hardening work.

 

When you do it like this in most cases you wont see everything at all but the most will happen around the reflection of your light source.

I will try to explain what you can look for with pictures from Aoiart of a Hizen Naginata.

 

 

Now you "play" with the relfection of the light and different things will be visible close to it.

 

1. This is actually the first thing i would check if i look at the Hamon of a blade. Is this Nioi or Nie Deki ?  (I will answer this later in case you want to guess yourself)  

 

2. Around the reflection of the light on the Ji you can see the Ji-Nie. In this case the surface is full of uniform reflecting little dots what is known as the Konuka Hada of Hizento.

 

3. Look how wide the Hamon is , this could be part of point 1.  This varys much from wide Hamon of Soshu blades to very thin Yokoyama school Hamon for example.

 

4. There are some Ashi that are not very long and dont go down to the edge, they make this Suguha based Hamon more a Ko Midare in my opnion. These are part of the activitys in the Hamon called Hataraki.   (the disconnected from the Hamon Ashi are actually Yo)

https://markussesko.com/kantei/ Hamon and boshi#1 of this articles will get into much more detail about this and all the other articles there are also full of useful Information.“

 

I wrote this in another thread some time ago but I think It could also help here and I don’t have to write it again on my phone.

My take on the issue is a bit unconventional. The problem is that even if you can't see the crystals it can still be nie, just a very large or very densely packed martensite area. Its not uncommon for Edo period works.

To me the comparison has to be between how the blade appears with glancing light (kissaki towards the light source, observing from the nakago) and side light (observing from the top, light on a side).

If both are comparable its nie.

If glancing light reveals much more, its nioi.

Thank you so much @DoTanuki yokaiand @Rivkin

 

What I do notice know is aim the blade towards a light source and sort try level my eyes with the surface. This shows the hamon very well. This can't be done always on natural light? Depending on what time of day.

Excellent education @DoTanuki yokai thank you!

Paz,

The picture you share shows hadori nothing else. Nie and nioi are both martensite (juste a matter of size). Nioi is always present in a nioiguchi even in a nie deki hamon;  if you can have a hamon in pure nioi, you will never see a hamon with only nie.
