I just got my 561 yesterday and I love it! I have a couple issues, first I can hold handle and move blade up and down and watch the lockbar pop in and out pretty bad. Second the detent is very soft. Now my question is if I take the knife apart (I know I can do this properly) and slightly bend the lock bar in will this fix these issues? Will this void my warantee if I do it? Don't want to waste Kershaw's time if this is all they are going to do. Let me know what you think.
