Michael, I noted this thread a few weeks ago, but at the time was in a situation where I could not post to the Forum.

It is difficult to give an iron-clad opinion based on a photo, but what immediately catches my eye is the apparent flaw in the opposite side of the blade to the side with the inset. This flaw appears to correspond in position to the area with the inset. From what I can see here, I'm inclined to think this inset is a repair intended to strengthen the flawed area.

Thanks both for the added information!

I also guessed that it wasn't that old. But older than 21th C.

On the flaw/inset they don't exactly correspond IRL in position.
But the top flaw is very close to the top 1/3 part of the inset.
The lower flaws/dents don't correspond at all.
Do you have any theories how a flaw like this occured?
I assume it was after it was manufactured?

Michael

Hello Michael,
maybe like my guess at first view, a blowhole?

20thC works or later
later than 20th Century... Is the iron still hot ?

Detlef, what do you mean by a blowhole ?

Ps. I can imagine that during forging some flaws may occur and than you can of course decide to make some repair when this occurs in a stage where the product is already near its final form/shape.
But than is looks like the only flaw in this blade.
I really like the shape.

Michael, the flaws do not need to exactly correspond. A flaw can occur through the blade at an agle. If the one on the reverse side is even close to the patch, then for me, this would be a good enough indication of a flaw that occurred during manufacture.

I also do not understand "blow hole".
Flaws can occur for several reasons, mostly either a cold shut when welding, or because of a degree of hotshortness in the material. Whatever caused it is not important:- its there, so can it be fixed? That is what the maker---or maybe owner would have asked himself. This inlay, or inset, or patch or whatever you like to call it, would probably serve the purpose.

Hello Willem,
sorry for misunderstanding, I've used an online-dictionary. I mean a forge mistake. Maybe a inclusion from cinder. Nearly the same guess as Mr. Maisey mentioned.

Thanks Alan for the explanation on manufacture flaws.
I also didn't get Detlef's blow hole first.
I thought it was related to the esoteric peeping-hole in some Javanese keris
