I’ve noticed a great deal of design similarities between these 20th century Afghan axes and these axes from Oman, from everything to the design motifs, to the copper inlay, to the carving on the shaft.
An interesting piece of info is some of the Omani axes are imported from North India, which is a rather vague piece of info but might point to the fact that this design might have a Central Asian or Indian origin. Still this is shrouded in mystery for now.
