You misunderstand. We're only talking about the cloak. The chakra arms Raikiri Chain cut off were still an extension of the V2 Cloak. It was probably easier to cut because there was no body behind it but it doesn't change the fact the cloak was breached. Raikiri not piercing the cloak has nothing to do with my original point because I said Raikiri Chain cut the cloak so why are you rreminding me the regular Raikiri can't? I compared Karate Chop to Raikiri and said they were similar in how they worked, not in power because the former is far more powerful than Raikiri.
The cloak is more durable than the arms as the arms are just chakra.

The chakra that forms arms and in this next case the body is clearly different.
