Something has both advantages and disadvantages

[symaa]

Hello,

When we talk about something has both advantages and disadvantages "Une arme a double tranchantes " we say for instance:

Technology is a double-edged sword.
or:
Technology is a two-edged weapon.

Could you please tell me which sentence is correct?

Have a nice day,

According to dict.cc you can either say double-edged sword or two-edged sword.
You can also say it cuts both ways.

Cheers!

I don't, though some people may use this term. I believe that it is an older term and not used very much.

Thanks a lot for the new information.
Best wishes

Thank you teacher.
Have a nice day.
