Tack or staple puller?

[CdK]

Good morning,

I acquired this tool in an estate lot a few years ago, it was a mixed lot and I was primarily after the many old hole punches so gave it no thought as I did not know what it was.

It looked a little rough and maybe hand made but this morning I cleaned it up and realized it was probably manufactured as there are a number of features that did not indicate one-off or hobby made. (Some hobby made tools can be awesome TBH)

Google image search calls it a tack puller or staple puller. What have I got and how can I use it?

Not sure that's what it was made for, but it sure looks like it would work nicely for that purpose.

It also looks like it could be a creaser. Yes, my guess is a creaser.
