Hello, I recently bought a Delica 4 and am loving it. Love the shape, sharp as all get out, very nice knife. I do, however, have a question or two on it. When I press on the baclock to disengage the blade, the blade freely closes about 90 degrees (halfway closed). Should the pivot be loose enough for that to happen? I've noticed that there's no horizontal blade play when the blade is open, however when closed the blade is easily moved from side to side, not remaining centered. Does this indicate the pivot needs to be tightened? Please correct me on my terminology or ask questions, I'm new to this.
Thanks for the help!
