These knives were recovered from the steamboat Arabia, which sunk in 1856. It was buried under 40 feet of mud. These knives are on display at the Steamboat Arabia Museum in Kansas City Missouri. https://www.1856.com/ My apologies for the crappy photos! I could not use a flash, so the photos are not very good. For anyone interested in history, I strongly urge you to visit this most excellent museum! I have visited them 4 times, and see something new on every visit.
