34. The TSA confiscates and auctions them, and

Sometimes donates a few. Some are auctioned in bulk, by weight; the better ones are auctioned individually. The states apparently handle their own auctions.

Here's a link that tells you how to attend these auctions in each state.

I learned about this from a TSA agent who was shopping at the Army Navy store I work in.
He said they confiscate tons of Swiss army knives people leave on their keyrings, when he saw our display of them. I also get a fair number of people who are looking to replace one that was taken when they flew. A few people have told me about touring the factory when they visited Switzerland.

Did your friend get a new one to replace the one they took? It wouldn't as special as the one her husband carried, but it would be nice to replace it. Perhaps you could get her a new one?
The little basic ones cost under $20; basic medium versions can cost up to $50. They also make many deluxe and limited edition models that are much more costly.
