double tranchant

"This is a double edged sword" saw this sentence in post on the forum, leads idea to give french equivalent

you can say "c'est à double tranchant" meaning whatever you choose there a bad consequence or disadvantage.

Thanks very19. I enjoy hearing and learning colloquialisms and then I try and get them into conversations, often by contrived means.

Thanks very19, keep them coming.

What, for example, is "It's raining cats and dogs"in French? Is it the same as "temps de canard"? And what is "temps de grenouilles"?

I was told that one by our neighbours some years a go and I think it was 'Il pleut comme vache pisser' or words to that effect !!!

not accurate enough. So further explanation:

The exact use is when your positif choice can also leads to bad consequence or disadvantage.
Can have very good consequences as very bad, talking example of a possible solution to a problem.

example:
Tourism is "à double tranchant", boosting the economy but damaging the environment.

"Le crédit est une arme à double tranchant qui, mise dans les mains de prêteurs incompétents ou sans scrupules, rendra les pauvres encore plus pauvres"
=
Credit is a two-edged sword: in the hands of unscrupulous or incompetent lenders it will make poor people even poorer

Some expressions classed from more common to not often use (from my point of view):
Il pleut des cordes
Il pleut à seaux
Il pleut comme vache qui pisse" as said by Tony
Il pleut à verse
Il pleut des hallebardes

AHHHHHHHHHHHHHHHHHHH
