I recently watched the Coen Brothers' new western anthology
The Ballad of Buster Scruggs and spotted a few traditional knives. (I'm always on the lookout when watching a western, as there are bound to be traditional knives, particularly fixed blades, to be spotted somewhere.)
The film is a collection of six different stories. In the first, which shares its title with the film, Buster Scruggs (played by the wonderful Tim Blake Nelson) enter a saloon where he has to check his weapons at the door. On the counter of the weapons-check station, you can see a big hunk of wood with several traditional fixed blade knives (and one hatchet) stuck into the top of it.
There are a few other instances in the film where you notice fixed blade knives on belts, but they're never removed from there sheaths and aren't really noteworthy.
As for pocket knives, I only noticed one, in the film's fifth story, "The Gal Who Got Rattled." It appears only briefly, as two characters are sitting around a camp fire. One pulls a plug of tobacco out of his shirt pocket, bites off a bit for himself, then offers it to the other fella. The second guy pulls out a pocket knife, opens it (pushing the blade open with his thumb on the edge), then goes to cut himself a piece of tobacco from he plug.
Here you can see him opening the knife.
And here are a couple shots where you can sort of see the outline of the blade. Looks like a spearpoint.
One thing I would've never caught while just watching the movie, but noticed as I was going through and pausing the scene over and over to get the screen grabs, was that
before opening the knife, when the plug of tobacco is tossed his way and the actor moves both hands out to catch it, you can clearly see the knife blade is already partially open, his fingers carelessly placed between the blade's edge and the handle. I'm guessing that's a prop knife with no sharp edge.
