I remember seeing an exhibit on those guys in the 70s as a kid. It was probably at the Anchorage museum, or Dad dragged me off to Fort Richardson--it has been way too many years ago. Anyhow, even then I was a bit of a knife nut so some of it stuck in my head. There were butcher-style blades that looked like Old Hickory; the striation/lines running parallel to the blade were about the same. The handles were mostly just local wood, some were antler, and one was walrus tusk. The only other thing that really sticks out is that all of the knives looked like 100 miles of hard road, they probably got donated at the end of their useful life. Note that there was no ulu. The round or curved blade shape was for women only, and a man found using one was about as shocking as seeing pink thong underwear on an NFL linebacker. It's not taboo anymore, but old ways die hard.
