that's because the jambiyah/koumiyyah/khanjarthrougout the arabic world is used with the point down and the inner curve as the main cutting surface, Most are fully double edged, and westerners and those not used to the old ways assume it's used like a short sabre/talwar.

See also this western sword dealer/teacher's take on this, and read the comments below, especially what id now the first,

I'm a descendent of a nomad tribe from the Arabian peninsula. To use correctly, after the small penetration with the tip forward the holder makes an outward cut like with a kukri. So it never intended to make a full stab in that way of holding. Btw holding it upward with the tip backward was funny to see because in my culture is a sign of lacking the experience with this dagger ".
