guardless nimcha

[ariel]

In his book "The races of Afghanistan" Henry Bellew discusses Nimchas, "The Half-and-Half", ie mixed race or converted "Kaffirs"

And Elgood and others explained that the very term Nimcha stems from Arabic Nim, half, and -cha, a diminutive suffix.

Thus, nothing specific sword-related. Kind of "Shorty":-)
