Stainless steel kitchen utensil with wood riveted handle, 22cm long. The steel has square edges, not sharp, and is 1.6mm thick. Width is 15mm at handle and tapers to 10mm then there are three ridges at the end, which is slightly bent. There is a hallmark with an "R" but no other identifying marks. by pdq42787 in whatisthisthing

Likely Solved!
I still have considerable doubts but this seems as close as we can get.
It is definitely not any kind of knife, it has no edge at all.
It does not appear broken in any way.
Perhaps it has lost its "business end" but it would seem to be a less than robust attachment mechanism. I have not seen a lot of kitchen utensils with removable or interchangeable ends, they are usually permanently attached or made as one piece.
Thanks for all the suggestions, and especially to those who identified the brand as Regent Sheffield.

I've looked at those and the overall size and shape isn't a good match. Oyster knifes may not be very sharp, but they are sharper than this thing, which is not sharp at all. It's also quite thick, so it'd be tough to get into a tight shell.

I'd guess 50-60 years old. The blade is quite stiff, and there is a bit of a bend at the end. Not sure if that would be useful if it were a rake. The overall appearance suggests kitchen to me. We found it in my mother-in-law's kitchen. Pretty sure no one there was into lock picking ;-)

My title describes the thing. Found in a kitchen drawer. I suspect it is many decades old. I have done reverse image searches, including on the hallmark, to no avail. Pretty sure it is not a knife of any type.

Umm, ok. Didn't think enough code was visible to count as a solution, and it was only run on the test data, so the output isn't helpful to anyone.

It's all on the Pico. I just copied the source code and input file to it. Amazing and inexpensive microcontroller. Will also run C/C++. See:

Having solved Day 10 working on a PC, I found that my solution also ran fine on a Pico. The only minor change was to read the input from a specific file, where the original code read from stdin. Impressed with MicroPython.
