When to use
ないことには~ない: unless X happens, Y cannot (行ってみないことには分からない).
Explanation
The ないことには grammar point is used to indicate that something cannot be done or achieved unless a certain condition is met. This pattern is formed by attaching ないことには to the negative form of a verb, followed by a negative outcome statement. It often appears as V-ない + ことには + V-ない or a negative expression.
