Sori ga awanai

Japanese idiomatic sentences #3 with sword

Sori ga awanai（反りが合わない）= The curve does not match

One of the Japanese sword blades’ uniqueness is its curve. Each sword has a different curve and length. So, a scabbard (sheath) must be made to match to fit its blade shape perfect.

Therefore, if you try to put back your sword into a wrong scabbard, it will not fit in. This means that you do not get along with that person; e.g. unmatching chemistry.

On the other hand, there is another idiomatic expression; “Moto no sayani modoru（元の鞘に戻る）” which says that a sword returns back to its original scabbard and that sword fits well with its scabbard. This expresses that you will reconcile with a person.
