Grapefruit spoon?

I would say a grapefruit/kiwi spoon (just guessing)

But a grapefruit spoon comes to a point. that looks like it would be difficult/too large to use.

I think it has something to do with spackle or plaster or something like that.

Mini trowel? Strange!

Fish scaler?

Maybe it's some sort of corer?

I also think its a fish scaler...

I don't know what it is, but I'd use it to scrap seeds and goop out of pumpkins and other large squash!

It reminds me of this bread slashing tool from King Arthur. http://www.kingarthurflour.com/shop/items/lame-bread-slashing-tool
The main difference of course being that this tool has teeth which may catch on the dough in an undesirable manner.

Ask America's Test Kitchen. They always have an answer for things like this.

fruit sectioner (sp?)

It's a mortar trowel for tiling in a small space

Oyster Knife?

Looks more like garden equipment than kitchen equipment. If I had one, I'd use it to take root-bound plants out of their pots.

Honestly, it looks like some of the tools we used to throw pots in ceramics class.

Wow Sarah Hope thanks for calling my attention to the lamest unitasker ever created haha...I can't believe they really sell that! Too funny.

My first thought was that it would be perfect for shaving coconut - you'd hold it like you were whittling wood, pushing and you'd get a shave on top.

It also does look like a ceramics took like sunandtea said. Scoring and all that jazz.

it does look like a lame, as sarah hope posted, except i have never seen one with ridges. oh and mimee25, it is a unitasker, however, it's quite useful, being curved, when you use it to create slashes on the bread, it gets under the dough, allowing for proper expansion of the bread during baking. most professional bread bakers use them.

Actually, it's a woodworking tool. Notice the way the blade sits flat with the handle raised at an angle? It's for sawing the banding of veneer or light wood applied to hide the raw edges of shelves, tables, etc. It saws the banding off flush with the board itself.
It wouldn't work as a lame, all those sharp teeth would tear the dough.

Well...it looks an awful lot like a coconut scraper...which I've seen a few versions of...they are often hand fashioned...notice how the edges are similar to the one in the link...look up coconut scraper and you'll see about a zillion different versions with very similar teeth...a saw or knife would have proper serated edges and not be this simple..

It seems unlikely that it's a woodworking tool, as the handle (and the handle joining) is not sturdy enough for that...nor are the teeth a true saw, saw teeth are bladed...this is simply teethed...

how about for making butter curls?

I second the coconut scraper. The ones bought at the Asian food markets have similarly serrated edges and are square in shape.

i agree, its a coconut shaver

Looks to me like one of the tools Ive used for pumpkin carving

wouldn't a coconut shaver be round?

I believe that it is a home tool but perhaps not a veneer saw - I used something like this:

To crack the seam of windows that had been painted shut.

@ JDK in OK

I like the sounds of that use.

It's not an Oyster knife.

I vote for veneer tool.

-Or a faux-graining tool -you rake it through the paint to create "grain".

mortar tool

I like the coconut-scraper theory, although I'm not entirely convinced it's a kitchen tool. You could also check over at This Old House--they accept requests to identify old tools.

My guess is an avocado tool...since I just saw something kind of similar in the Williams Sonoma catalog
