I think Nakano is refering to putting it back in your pocket and having the wave partially open the knife. I have tried it without this experiencing the wave openning it. However if you are not careful and slightly turn the knife I can see how the wave would catch the pocket.
My guess is these are the exact handle slabes that go on the regular CQC7
