As noted, some of the places you plan to visit will have metal detectors. You can call ahead to check if they have metal detectors.

The state's gravity knife ban was repealed this past Summer, and thus the wrist flick test that was used by NYC to abuse folks carrying common locking blade pocket knives has gone away, a slip joint knife like a SAK wouldn't have been an issue in any case.

Always keep your knife fully concealed in your pocket, which again, is what you'd do anyway with a small SAK which doesn't have a pocket clip.
