Mine is just fine. The bearing setup is actually very well done, they are cased in plastic washers that fills in the gap to help keep dirt and dust out, but are not "sealed" per-se, so you can wash them out, oil or grease helps slick them up while they break in, but they are plenty smooth dry afterwards, so nothing to attract dirt. My complaints with my 561 are few, pretty much minor gripes of an OCD knife knut. The lock bar is bare Ti, so it sticks, and can feel a little gritty closing as it grabs the blade tang, coated locks are way smoother, even a small patch of DLC on the locking surface would have helped, a steel insert would have been even better. Mine was tough to open with the studs when new(any pressure on the lock bar presses the detent tighter), wore the detent in with contant flipping over months, and both slicked it up and made it way easier to open with the studs, but it has slight up/down play when folded. The G10 scale also doesn't quite match the liner under it, and covered the lock a bit more than I liked, so I shaped it a little deeper to make the lock easier to reach at no expense to comfort. All in all it is a wonderful blade, and well worth the money, light for it's size, great blade shape and grind, definitely tough, and Elmax has really become my favorite steel. IT sharpens and polishes easily, gets a very fine hair popping edge, but is very tough, rust reistant, and holds and edge for a LONG time.
