What is this utensil?

My MIL found this in her kitchen. It kind of reminds me of something you would use to eat crab with but I have no clue what the serrrated edges would be used for.

That is awesome. Thank you so much.

I found it labeled as a Japanese fish scaler, complete with picture, in a package labeled fish scaler. Thanks for the good lead, Manybears!

I think it might be a fish-cleaning tool... (based on my limited google success).

Same here,found a few pages of what is this? that needed translation, All said thought it was fish scaler knife. Interesting though.

More details. Both edges are knife sharp, The serrated edges are sharp too. I put the blackberry in the picture to give sense of scale.
The writing on it says:
A.B. Ferrator
Stainless Steel
Made in Sweden

That kinda sorta looks like a knife I'd use to cut long sheets of things. Like carpet, linoleum or vinyl. Doesn't look strong enough to be a metal cutter, like a tin opener.

Sure it's not an old surgical tool? Looks scary! lol :)

In a sense, it reminds me of a very old fashioned can opener, but I know it isn't.

The serrated side is perplexing.

I have one of those old fashion can openners at our cabin and it does resemble it.

I too am curious about the serrated side.

It looks like it could be used for sectioning citrus, I've checked my gadget catalogs or knife catalogs show it. Interesting though.
