Unknown Wm A Rogers Silver Plate Pattern - Clearly Marked

Hi. I’d like some help, please, identifying this pattern. Can’t seem to find it anywhere.
In case the photo is inadequate, the mark reads Wm A Rogers A1, plus a patent date…“PATFEB1801”. At least I think that’s what it is, which seems unusual, although it likely refers to the “technology”, not the pattern. It might have been an innovation back then. Other butter picks – or nut picks – (or perhaps it’s an olive pick), don’t have such a long twisted end, as far as I can see.
I’d so appreciate any help. Thanks.

It appears to be Warwick. Same patent date of 1901.

Thank you … somewhat belatedly.
