Received the Sebbie this past Wednesday. After what I assume is the normal new knife opening and closing about a hundred times (by THUMB), I couldn't resist taking it apart. Did it at my well lit reloading bench and still almost lost a spacer. Did an unnecessary clean and then used Gun Butter on and around the bushing area. I hadn't noticed the difference in spacers when I took it apart, so it took awhile to establish that the large one was supposed to be in the rear part of the knife. When reassembled, the blade easily opened with light pressure from my thumb. I'm very pleased with the knife and it has become my EDC for sure.
