The blade and knuckle guard of khanjarli and chillanum are virtually identical. 
 In fact, both are the same dagger with  only ethnic difference in decoration, i.e. contour of the  handle.  We see the same principle in local varieties of tulwar handles, in pesh-kabz/ “karud”/ choora,  S. Arabian vs. N. Arabian vs Persian shamshirs, Yemeni janbias etc, etc.
