If you shove the knives really deep in your bag then you cover them with black bin liners and tape, customs won't notice I got 2 knives back from Morocco and they didn't notice :3
I think you'd be a lot more fucked if they found them wrapped up in bin bags and tape than if they just found them loose in your bag though. You wouldn't have plausible deniability that's for sure.
I love how the woman sitting on the right seems completely uninterested in two grown men pretending to try and kill each other with pixelated weapons.
