This is very interesting Martin, On looking carefully at the sketch I note all three men in front are wearing a weapon like this. Perhaps this is an entirely new weapon?
On the other hand ~ It is interesting trying to fathom how this was used except for the fact it looks vicious and it could be stuck into someone...it seems over curved... but on looking at related battle fields was this a special weapon to hamstring horses...? see

Quote" On the way to relieve General Gordon at Khartoum, Count Gleichen (Guards Camel Corps) after the battle of Abu Klea, described the native weapons lying on the battle field thus:
"Arms of all sorts and broken banner-staves were scattered over the field; spears in hundreds, some of enormous length, javelins, knobkerries, hatchets, swords and knives, I even found a Birmingham bill-hook, with the trade-mark on it, in an Arab's hand, sharp as a razor and covered with blood and hair: how it got there I know not, so I confiscated it for the use of our mess."Unquote.
of knives it said ~
Quote" Knives offer the greatest variety in shape, decoration and materials used. They were double-edged and maintained at razor sharpness. The hooked blades were for hamstringing horses and transport animals, and were
used with great effect against the 10th and 19th Hussars at El Teb."Unquote.
