Hi. I'm left handed and considering the purchase of a Civilian with G10 scales. I plan to move the clip to the other side of the handle by drilling and tapping for the screws. Doing this will require me to dismantle the knife for drilling. This leads me to my question - is it possible to dismantle this knife, ie. is it held together by screws or rivots? In all the pictures I've seen I can't tell. Thanks for your time.
