: Given that ESC and I both posted simultaneous answers on this, I thought I'd idly googlefight "two edged sword" versus "double edged sword". The results? A very inconclusive 198,000 hits for two edged, and 184,000 for double edged. My instinct was instantly for two edged. I wonder if it's a UK/US thing?
At swords' point. In deadly hostility, ready to fight each other with swords. 1
Poke not fire with a sword. This was a precept of Pythagoras, meaning add not fuel to fire, or do not irritate an angry man by sharp words which will only increase his rage. (See Iamblichus Protreptics, symbol ix.) 2
To put to the sword. To slay. 3
Your tongue is a double-edged sword. 4
You first say one thing and then the contrary; your argument cuts both ways. The allusion is to the double-edged sword out of the mouth of the Son of Man-one edge to condemn, and the other to save. (Rev. i. 16.) 5
Yours is a Delphic sword-it cuts both ways. Erasmus says a Delphic sword is that which accommodates itself to the pro or con. of a subject. The reference is to the double meanings of the Delphic oracles, called in Greek Delphik muchaira.
