I think people are confusing "Metal detectors" with "X-ray machines", the two are completely different. I doubt metal detectors would beep on a plastic knife being brought through (Though I do NOT recommend it, especially since some people are randomly patted down) but there's a very good chance the knife outline would show up on an X-ray view.
I don't think these would do well as trainers; too rigid and pointy. Use rubber knives! CS is not noted for their political correctness but THEY say these are not trainers. Be safe, folks! A pointy piece of rigid plastic thrust with force--OMG is that what I ate yesterday!? Don't let it happen to you.
