What does the phrase double edged sword mean?

According to Merriam-Webster English Dictionary, Your Dictionary, and other dictionary apps, the English phrase double edged sword, also seen as “double-edged sword,” is an idiom that describes something that has or can have both positive and negative effects or favorable and unfavorable consequences. This is often used to describe something that has both good and bad aspects to it, or when making a choice where something bad happening is inevitable. This is a benefit that is also a liability, or something that while it may seem positive, also comes with risks or potential obvious costs. 

Someone might have to make a decision between two options that are both double-edged swords. In this case, they may choose to make a pros and cons list, or enlist their friends to help them weigh the positives and negatives and make a decision. For example, if someone got the opportunity to leave their current job in exchange for an amazing opportunity, but the new job required them to move across the country, this would be a double-edged sword for some. If the person likes where they live, the negatives would be having to move and having to leave their friends behind, while the positives would be an amazing opportunity for career advancement and a higher paycheck.

What is the etymology of the phrase double edged sword?

According to The Village Idiom and Word Sense, the phrase double edged sword may have originated from the Arabic expression of the same meaning, “سَيْف ذُو حَدَيْن.” Additionally, in the Bible, the word of God is described as being “sharper than a double-edged sword.” This idiom was first used in the 15th century. This expression likely did not originate in English because English swords are almost exclusively double-edged, whereas Arabic and Eastern swords are curved and edged on only one side. Thus, it would make more sense to specify that the sword is indeed double-edged.
