From what I have observed there are two types of Indian tiger tooth jambiya, and they are a type of jambiya....one type has a thick blade and the tang is also thick. The other type is a much less well made type.....a thinner blade, a bit flexible even and also thin at the tang.....for a person of less wealth, or a youth maybe, who knows but there is a world of difference between the two types...I also have one of the lesser types and it is certainly not wootz. hard to tell with a photo but in hand the difference is clear.
Miquel can tell which type his is.
Thin blade, thin tang, not wootz.
Thick blade and tang.
