N2s, I think the haladie you show on the first picture should be turned, so the ‘upper’ blade could be used for a forward stab and the ‘lower’ blade for a backward stab. What do you think?
It is a very nice haladie you found on the net

Valjhun, it is true that the two haladies have split blades, but the one from the museum also has a round whole. I don’t know the reason for this, other than when it comes to the haladies a stab wound would not/could not be very deep, due to the split blade, but the cutting effect must have been nasty. I wonder if the serrated blades like these were not meant more for slashing than for stabbing, and the one n2s shows maybe more for stabbing – pure guessing.
