All About Pocket Knives

Hey guys,
I know a guy down the road that has a case knife for sale. It is marked viking on the sheath and on the tang. It is marked case on the tang also. I've never seen one, but maybe someone on here has. On the handle it is marked Case xx tested. Its in fair condition showing some age. He told me that this was a promotional knife? What do theae go for? He wants like $125.
thanks

If I recall correctly, VIKING was a brand used by E Weck and Co of New York, a firm that had knives made for them on contract. I have seen VIKING marked knives but never one with Case markings as well. It may well be real and it would be interesting to see photos of it including the markings.

my mistake, the knife is marked viking e.w. New York on the tang. Case is not marked on the tang, but case tested xx is on the handle

Here is another Viking knife
marked Viking and E W new york under that
