I have a Kershaw chive as one on my EDC knive, the others are a Kershaw blur and a small SAK. however the chive in question lately isnt wanting to spring open, ie the assisted opening mechanism isnt working correctly. it will spring open about half way then stick. The blade moves freely from closed to open with assistance but not on its own. Has anyone else here had this problem? If so what did you do to fix it?
