Me and Neil both had a mantetsu blade with wavy hamon.

Thanks for posting that Chris!  I only had 3 (now 4) in the "MI" line of blades.  Two are Ren stamped and two are Koa Isshin.  Nice to see that one.

 

What would you say, still oil quenched?  or water?

Chris:

I know ara-nie is sometimes done intentionally, however could this also mean the blade was too hot when quenched?

Ara nie is a sign of tamahagene, hardned in water. On koto blades some said it is a sign of uncontrolled heat und a ugly thing that indicates lower quality and value. 

Ara nie on Gendaito is often seen and a proof of nihonto.

 

I found ara nie most attractive. But i dont know why it is on a mantetsu blade? 

Martensit isn't build in oil and not on industrial steel.

Dang!!!  So, we are possibly seeing a custom order Mantetsu made with tamahagane - fully traditional, gendaito?

[vajo]

I dont know Bruce. Thats why i ask Trystan if he had ara-nie seen on his mantetsu. Btw it doesn't matter which kind of hamon. Martensit only grows in  high carbon steel.

 

I was thinking that ara-nie needs water quenched. But i found a picture of a chinese T-10 (selfmade Tamahagene) which has ara-nie too. And this sword is not hardned in water. But i think that mantetsu from facebook was water hardned.

Yes i think it was traditional made.

Here is some old photos of my wavy hamon Mantetsu,it's currently at my friend's place.

Thanks Trystan but the kind of hamon (notatre, gunome, suguba or something else) isn't the question.

I can't see any signs of ara-nie in the pictures.
