Afghan Pulowar blade type?

[ariel]

OK, just as an afterthought: re. " Afghani regulation khybers".
By definition, " regulation weapon" is a highly standardized one, manufactured in bulk, according to a design approved by a central authority and ( very often) at the same factory.
In short, a large mass of identical twins.
Here are two allegedly " regulation khybers"

One has two grooves, another has one. One blade has a stamp on the ricasso and is numbered another does not. One has a shield-like languet, another does not.The D-guards are of a different contours.

The conclusion is inescapable: there is nothing " regulation" here. Just a similar idea expressed in different " languages" with different parts including imported blades, with or without governmental stamps at a defined position.

And if anyone can please explain to me how these blades could have anything in common with the classic Afghani khyber except for being short, I shall be very grateful:-)
