To whoever just Goggle'd...

"can i take my pocket knife into disney" and ended up on our blog...

The answer is no. At least, not if a small part of the pocket clip is visible, and some freakishly attentive old lady happens to notice it while you are passing through "security."

So just keep it in your pocket, and you will be fine. Along with anything else you would like to sneak into the place.
