what is this

Seam ripper/remover for disassembling something needs takin in or lettin out.

Perhaps some very specialized seam ripping; my wife is a seamstress and the run of the mill seam ripper I see every day isn't quite as elaborate as those.

I'm not a seamstress but tend to agree, especially when I saw the double bladed unit. (for double stitched seams like on jeans.)
Also some with right or left curves.
Do I assume they are quite sharp?

The one your wife uses (LOL, I have one) is kind of one size fits all tool.

Got a hunch there's more seam rippers of different kind & nature than there is bottle openers. Got 1 sister who can do such with a straight razor or razor blade scare me. Other sister I think drove a husband off makin such to her design & desire most of which resembled crochet hooks and pushers if such be. Poor husband was some kind of fancy tool maker at least till he up & run off.

Of course they could be Layovers, to catch meddlers or even a plug out of a Shikepoke.
