"Mad Mahdi" Dagger

[Aurangzeb]

Hi all!!

Thanks for all the help on my Sudanese dagger.I personally think the dagger might have even have been tuked in the sash of the warrior.The coins depicted with the dagger are only a small fraction of my Islamic/Sudanese coin collection.I do have several questions:First,are there any recommended books on sudanese weapons and the British-Sudanese war?Second,this question may seem dumb but,Why is Sudan sometimes called"The Sudan" instead of just"Sudan".Also the tip of the dagger protrudes from the sheath slightly,chould anything be done to fix the minor problem? Finally,what is the fighting style with this dagger type,is it like the fighting style with a kaskara?

Any further info whould be appreciated,thanks to all...hopefully i'm not beeing a pest.
thanks all
