τμητήρ
I am trying to understand the etymology and the relationship between the meanings of this word. It could be translated as a 'hero', 'iron' adj., 'one who cuts or severs, destroyer', the one who cuts or divides', 'the one who destroys, destroys, with iron', 'καταστρεπτικός, τμητὴρ σίδηρος'. Probably, the problem I am having is to understand the relationship between 'hero', 'iron' and 'destruction'. Could anybody comment on it, please?
Also, if you'd know the first known use of the word, please? Thank you.
