A few closeups. Both sides of tip. Typical style of nidai "Shige" with the upwards twist to the left and the lower horisontal bars compared to shodai. Do I also see masame?

Heh, mine got stuck in customs for 3 weeks...

Geraint it is ryoshinogi. It reads Echizen ju on the reverse. Why? I guess that was same as with their swords. Tradition or any particular reason, I do not know.

Me too. That was what first caught my eye. Both sides equally nice towards the point.

Just wanted to share my latest buy. A nice little Yari by nidai Shigetaka. Conny

Tutankhamun's meteoric iron dagger

Which is exactly how I have done with knife blades made from meteorite. Work hardening is what I guess has been done to the egyptian knife in question. Conny F -

If meteorite iron is heated, forged, carbonized and afterwards heated and water quenched. There would be nothing left of the original crystalline structure. Then only traces of rare elements like iridium would reveal the origin as extraterrestial. Conny F -

cofor22 replied to vajo's topic in General Nihonto Related Discussion
I can chime in a bit regarding meteorite iron and knife blades. As already mentioned the heating and water quenching would not produce hardening. I have made several knife blades from nickel iron meteorite. Edge hardening was done by hammering just as bronze edges are hardened to get the edge sharp and not lose bite too fast. Just the edge is hammered. It can get very sharp but never matching steel. Carbon in meteorites is usually found as graphite nodules but very seldom even as Diamond of type III. -
Do I see lack of distinct yokote or is it just images and light distorting?

I am struggling a bit to understand what I see in the hamon, ji, shinogi-ji and what different things I see at the surface and immediate subsurface of my blade. So, would someone like to describe what is seen in the following images. Nioi? Nie? Ji-nie? Chikei? In the photomicrograph, are the white areas martensite and the dark some other type of steel crystals? The area is part of the Ji-Hada. https://gemology.se/files/waki/ha_mon_ji.jpg https://gemology.se/files/waki/hada_micro.jpg Conny F

Got it, thanks for your input. I will focus on the blade for guidance. Conny F

I was thinking: If noone has seen a hot punched Mekugi-ana in a modern fake yari. That type could serve as an indicator we have the real deal in front of us. A drilled does not rule out real deal. I know many other signs can be seen to be used but some times butcher "polish" and pitting hides hada as well as hamon.
-
Enlighten me please. Hot punched or cold chiseled?
-
Well question was if anyone have seen a, for instance, chinese fake with a punched hole. If so, a punched ana would not be usable as indicator of anything. As a gemmologist I am used to analyze Gems and minerals and separate synthetics and treated stones from natural untreated. Then it is good with indicators to speed up the work. Conny F

Thank you Brian. Conny

Well that was an odd reaction to a very clear and specific question. Does that mean you would like me to elaborate? Conny F

... Yari with a punched Mekugi-ana? Conny F

Might be time for a new sword !

I could trade the item in the linked files for a nice blade... ???????? Not gold but close. https://gemology.se/files/waki/VID_20190710_175517.mp4 https://gemology.se/files/waki/IMG_20190710_174745.jpg -
Thanks, as a beginner I would not argue. It could be described as notare with ashi. It is not easy to separat all nuances. Conny F
-
Are the images not good enough to say something about hada? I can not categorize myself. Find it hard. The true hamon is easier and I call it gunome-midare.

Thanks. Conny
