What is a synonym for saber?

Could you please enlighten me on what another word might be used in place of "saber"? Is there perhaps a term that conveys the same essence or function as a saber, yet differs slightly in its lexical expression? I'm seeking a synonym that accurately captures the essence of a saber, its characteristic shape, or its intended purpose. Could you assist me in identifying such a word, perhaps one that is commonly used in literature, conversation, or even in the realm of military jargon?
