Hello all. Recently purchased a Lionsteel ROK in all black. Absolutely beautiful knife BUT it is way, way too stiff. No way to open it with one hand. It's a flipper, but in no way can I get it to flip. I'm too new at this to trust myself to take it apart so I just blew out the action with compressed air and applied some KPL. Didn't help at all. I emailed Lionsteel at the only contact email I could find on Sunday: care@lionsteel.it. Crickets. I emailed them again on Wednesday, same thing. Any advice? Thanks much in advance.
