I had always thought the nimcha hilt portrayed a stylized horse. IMO it is important to maintain consideration for an independent evolution of form… When compared to the "business end" of an edged weapon (though itself quite diverse in appearance), the hilt is comparably wide open to artistic and stylistic interpretations and/or variations. Given the rich history of edged weaponry in many cultures, might it be possible two distinct peoples may have thad he similar idea of portraying a stylized version of two different animals in roughly the same fashion?
