I visited the Heinz History Center in Pittsburgh today, and there were a lot of interesting things to look at. Learned quite a bit, and had a good time. Among some of the things that stuck out to me was a historical reproduction of a knife that was taken on the Lewis & Clark Expedition of 1804. I’ve been under the impression that outdoors knives of the time were similar to butchers knives, with a thin stock. I thought super-thick knives were strictly from the modern era. Apparently I was wrong. The knife rivals the BK2 in terms of thickness!
