If you ever want knives, you can get a fascinating set of them by looking out for the TSA/Airport confiscated items auctions.

Hawaii's one is at https://auctions.ehawaii.gov/dot/welcome.html. I had a boss when I lived in Hawaii that would bid on them, occasionally brought boxes of the random "sharps" (as they were called at the time) that had been confiscated from people by TSA. Some of it is somewhat surprising that people still had on them when they got to TSA, like high quality 18" long machetes.
