Salaams all ~ I have a Karabela.... The weapon came to hand for a friend who bought the item in Mutrah souk Muscat some 2 decades ago and is interesting since it has a dot on the tip of what appears to be a European imported blade ...and a typical Yemeni to Oman inter souk traded item. The design is clearly a local Yemeni copy of Peter Munich of Solingen style...(1595-1660) I believe so liked because of its moon phase ... and generally well respected blade...The moon phase also likely to have been copied by Munich from Juan Martinez of Toledo (mid 16th C)
