shit gets through all the time. There are plenty of stories of people bringing guns through that they didn't realize were in their carry-ons (concealed carry permit holders). I've unknowingly brought through knives before with no special attempt to conceal them.

I've also had items confiscated, so it works some of the time, but I think a dedicated person could limit their chance of getting caught to ~5%-10%.

Hey, I've done that! (accidentally)

It's a bit disheartening to have your mom's homemade jam confiscated, only to realize later that the boxcutter/utility knife that was in your bag got through just fine. I've also accidentally brought a 3-4" folding knife on a plane that I didn't realize was in my bag. They did find it the second time I tried to go through security, so... they are successful at least 50% of the time, I guess.
