OK s-k,
Here is El Lobo...showing up at a knife fight with a gun.....er, well, you know what I mean.
I don't have a definitive answer...(sorry)...but, here are some pictures for comparison...
Brown Mule...wood handles...1 birdseye pivot pin and 2 brass pins...sells for around $13 US.
Black Angus...ABS handles...pivot pin only...sells for about $7 US.
Note (if you can see, sorry) the top knife has blade etch, but only the two Cranes on the tang. The second knife has etch, two Cranes, and stamped name.
Sooooo, based on absolutely nothing...I say, because of the price, and construction, top is German...second may be Asian, possibly Italian?
My Brown Mule has no country of origin either...

...but I've had it for a decade or so. Can't explain that one...
I'll always seen and heard "Kissing Crane"... no plural ...even though there are 2, to, too, two Cranes.
Please disregard this if it makes no pence...cents...er, sense.
