First my congratulations everyone who has placed details here since this sword type is doubly difficult to analyze because of its apparent duality both in the Mediterranean and in the Indian Ocean.
The word Nimcha is Persian and used in the Baluch language also. I think that although it seems a short weapon this is only half the story since there are big swords around from the Moroccan side and those which were used by Band of London Officer Tobias Blose plus those seen a court in Morocco were examples from artwork. Thus what does it mean; Nimcha?

Nim means half not small. Nim o Nim means half n' half. Yak o Nim means half past One. Nimcha is likely to mean half sword....or half sharpened sword.

In most cases Nimcha have a heavy back edge and a sharp cutting edge suggesting that is the traditional style. A chopping slashing form; From Horseback or in its shorter style a cutlass.

Nimcha.

Thje weapon below with the sunlight from the window on it simply compared with the Butin charts gives the impression that this is a Nimcha and likely from Saudia.

The give away being the silver covered hilt and sharply turned pommel . Interestingly this weapon also has the chain knuckle arrangement and straight crossguard…Finials terminating in vegetal ends. The geometry in the centre of the crossguard suggests an evil eye design.. The blade has a heavy looking backblade and is curved to a point. The 5 silver sworls on the hilt suggest geometric hand of Fatima style.

The example against a jet black background is another KSA version.. and also has a 5 geometric decoration on the hilt in this case circular perhaps coins or coin lookalikes often copied. The weapon with three silver shots on the hilt is Yemeni. The other Nimcha is lengthways and has a black leathered hilt and is a Met Museum item...with a similar rounded rainguard.
