Its certainly an interesting thing Paolo, is it a weapon?
How long is is?

I think that your etching looks great as it has 'evened out' the colour of the steel.

There must be metal specialists on this BB who can offer a more informed analysis than mine?

Hopefully some other board members will have similar examples which can be compared.
Alternatively can you research the construction techniques on the net to get some clues as to how the metal is forged etc?

P.S. Thanks, the blade is a Bhuj.

Hello Paolo,

That's not wootz. I suspect that this pattern developed from heat treatment of monosteel (this usually happens by chance).

Regards,
Kai

Hi Kai,
I suspected it was monosteel, but I didn't know that the heat treatment on this kind of iron may cause this kind of (so wide spread) pattern.

Atlantia,
the kudi tranchang is 65 cm long (25,5 inches).
On Van Zonneveld book " traditional weapons of the indonesian archipelago" it is so described : a knife with a fanifully shaped blade and a long hilt, to which magical powers are attributed.

I remember seeing a sword with a 'wootz-like' pattern, Lew kindly re-educated me with the notion of shear steel, but this type of steel was mass produced late 19thC -early 20th C. It may be possibly 're-cycled' shear steel and forged into this interesting piece.

I think this is what my bladesmith friend calls the orange peel effect. Comes from over heating the steel during the forging process I think. This causes a a growth in the carbide stucture which ends up looking like an orange peel.
