Salaams ~ Ha HA ha !!!
Well yes there are lots of landmines still down there in places !
Flint tools are well documented by various archealogical groups in Oman including the French who have many specialists on the subject~ Trouble is with axeheads like these they want to know precise details with digrams of the site they came off .. You may have been on a flint weapon making site and dint know it... I am always finding arrowheads lying about in the desert ... ah well...Nice to have in your collection... easy maintenance.
