Nakano,
The clip will not work on that CCB you have, it does not have a hole larger enough for the clip to be attached. The attachment of the clip is via a Chicago Screw..2 piece screw.
I talked to James Sunday...you do not want to change the CCb you have...there were only about 10 of them made.
Buy the new CCB if you wish, it is a great uniot, I carry one every day...do you need more information on the mechanics of that particular piece?
I can tell you one thing, if someone takes your wallet from you, and I have tried this on blade and non-blade people, and it has always worked...if they take that wallet, the CCB is left in your hand, 100%...it is so simple and works beautifully...
