I think it's one of those "you know it or you don't" kind of deals.
I think it's also probably generational. It looks very old. My mother was one that collected every gadget came around and she never had anything like this. I guess we will have to wait until @andiesenji weighs in, she's usually right on the money .
As for using it for skinning or scaling fish, scaling maybe but that's where you start the skinning process and I can't see it working for that. I've worked around a lot of fishmongers and chefs while they are skinning fish and I've done a fair amount myself. I can't see using this thing when a good towel will hold it just as well. But then, what do I know. Whatever its original purpose was, it apparently didn't get much use because it Is still in almost perfect condition. Maybe it didn't work very well.
