Absolutely, but my experience included the checkpoint guy holding it against the Official Knife Blade Length Measuring Ruler, and saying “Very good, have a nice flight, sir”.
(I agree about serendipitously finding sharp or pointy things in one’s carry-on luggage only after one has reached one’s destination. Happened to me more than once, too. In any case, tiger-team experiments suggest that TSA agents regularly miss even bigger and more obviously contraband items such as handguns.)
