Land Of Lost Knives (and box cutters, wine openers, etc)

Every wonder what happens to all those pocket knives, box cutters, wine openers or anything mildly hard and/or sharp that the TSA confiscates are airports? You would think that these items which are so dangerous they can't be allowed on a plane, would be melted down into paper clips. Don't want these weapons to end up in the wrong hands, do we now.
But it seems that the geniuses at the TSA just hand the knives off to your local schools. Here is but a small sample of the potential hijacking instruments that were removed from the hands of law-abiding citizens and given to 3rd graders.
