What's the literal translation for 切れ味鋭い?


I know the 2 words mean "sharp". 切れ味 is a noun while 鋭い is an i-adjective.
Looking at an example sentence, it looks like 切れ味鋭い means "sharp" too:

> ステーキは切れ味鋭いステーキナイフがないと食べにくいよね。
>
> If (you) don’t have (a) sharp steak knife, steak is hard to eat.

If the two words separately means sharp, isn't it redundant to use the two
together?




切れ味 as a noun describes the sharpness of certain things like knives or mental
acuteness. Thinking of it as "level" or "degree" of sharpness might help you
better understand its use in tandem with 鋭い. Synonyms sharing the sense of
sharpness of knives include 切れ and 切れ具合.

You can say 切れ味のいいナイフ or 切れ味の鋭いナイフ, and they pretty much mean the same thing.
Redundant? Maybe, but it's nothing out of the ordinary. This occurs in many
languages. This kind of construction may not be as common in English, but it
does occur. For example, we say "good quality steaks" in a similar manner, but
we can also say "good steaks", or even "quality steaks" where quality itself
functions as a noun adjunct (or adjective, this is inconclusive and depends on
what dictionary you look at).
