Jim, the only floral Afghan work I can tottaly recall is on a Tribal Afghan kukri scabbard i have. Cant recall it on a blade. Think I have seen similar on Poulwar scabbards though but have no examples to hand.
Heres the bayonet marking with the above Dari script is a squarer form. {presumably the tools & level of illitracy amongst the armoury workers plays a role in the shaping of the letters.
From this thread.

I have no knowledge of the term 'cintamani' I know the presumed more usual meaning of 3 dots with Hindu weaponary but thats a different subject.
But I also notice 1,2,& 3 dots appear to be used for some linguistic or gramatical meaning in Dari.
i ll see if I already have photos of my Afghan floral scabbard online, if not Ill take & post some.
