I guess I'm sort of weird but I have a fixation on any knife that has to do with Hunting. These would be commercial knives. I have half a dozen Bucks some over 40 years old and a couple could probably have blade replacement and a bunch of others. Now, that said, has anybody tried or use one of the Ulu's? I don't know why but they have been intriguing me lately. Like I said, I guess I'm just weird when it comes to knives.
I have a couple of homemade ones made from a saw blade and a moose bone handle.
I also know a bunch of old Athabascan women that can perform surgery with the things.
