To decide if the blade is worthy there are a number of tests locals use including the ring test, the smell test, and the taste test. There is another which I describe as the three finger lift.
Lightly take the end of the khanjar blade up in two fingers and a thumb and slowly lift the item vertically ... If there is resistance and the dagger falls away its a good one ... If you can lift it easily its not so good...This happens as a blend of tests and may be done several times to satisfy the buyers mind..and looks like a complete load of jiggery-pokery but the locals swear by it...
