In the Naruto series, there are many occurrences where Naruto clashes with Sasuke. Their battles always end with a Rasengan against Chidori blast.

The Chidori appears as simply a mass of white electrical chakra in the user's hand, while the Lightning Cutter is more focused (and blue in the anime). tl;dr: It's still a Chidori but when Kakashi's using it, it's more refined and famed for cutting a lightning bolt ergo dubbed Raikiri.
Chidori was invented by Kakashi Hatake and the only users of Chidori apart from Kakashi are Sasuke and Sarada. Now, Lightning release technique are primarily used by ninjas in Kumogakure and they are the best in the business when it comes to lightning related Ninjutsu.
