Here's the thing. If I did this, I would also have to take away the players' dice and character sheets. Allowing them to keep their dice sets the stage for them to give me false numbers when they roll. Letting them keep their character sheets sets the stage for them to alter their numbers and items inappropriately. Those things are no different from metagaming. Cheating is cheating. If I'm responsible for one(and I'm not), then I'm responsible for them all and I have to remove all of it or else I'm being a hypocrite.
That would only be so if "metagaming" was actually cheating. It is at your table because of your prohibition against it, apparently. If you remove that rule, then it's no longer cheating. Then just use the techniques that were already discussed in this thread and you're golden. You're creating the issue to begin with.
