They stick at first in an interesting way. Mine did at first and I put some oil on it. Then it got worse, I washed it out with hot soapy water and then a dab of oil. Fixed!
It's an excellent blade and overlooking it because of confusion and interwebby whining does it a great disservice. I love mine, see it as the hidden perfect folding chefs knife which everyone seems to want but apparently can't recognize when they see it. I carried mine a lot at first and can attest at a farmers market Apples, bread, and Salami just fall apart in front of it. It's not very discreet as I noticed a few people notice the apple fall apart even though I palmed the blade. If I had to guess I would say tight tolerances and grit or locktite being partially dissolved is the culprit to early lock stick.
I hope it's not discontinued, at it's current discount it is an incredible deal.
