What kind of iron ?

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.
