ひだりきき
The readings are the kun'yomi vocab readings, so combine the readings of the words 左 and 利く together to get the reading of this one. It makes sense since this word is like two words put together.
私は左利きです。
I am left-handed.
左利きの人向けのハサミはありますか？
Do you have scissors for left-handed people?
あなたは右利きですか？それとも左利きですか？
Are you right-handed? Or are you left-handed?
