Hmmmm.. This is 70% catch to what I've imagined. Although it seems the segment blade tip lack of screw/foldable that makes it looked like it can transform into a grappler and some sort of trigger in the handle (That function is to transform the blade tip into a grappler).

I mean I imagine the Blade tip something like this. While the trigger in the handle is used to open the grappler. Holding the trigger will keep the grappler open, releasing the trigger will close the grappler back into the blade tip.
