Jambiya Blade Construction

[kahnjar1]

I would like some comment on the construction methods of ribbed Jambiya/Khanjar blades. I notice that a lot of these, particularly later/modern examples originating, particularly from Yemen, are constructed in two pieces, and then fused together in some manner. I personally have always regarded these as "not genuine", but simply a method of easily forging blades to attach to mass produced Jambiya. There are however some modern pieces which do have a solid blade. I have very recently taken a chance on one of these, described as having a "one piece blade", and although I do not regard it as old, it does, at a VERY cheap price, fill a small gap in my collection until I have the serious funds available to replace it with the real thing. I do not yet have it to hand, so can not really comment any further until it arrives. Pics are sellers.
Meanwhile, I would be most interested to hear comments re these two piece blades.
