What is this and what is it used for

I probably could use it "off label" to clean my BBQ; 😄

I am going to let others give it a try.

I think it can be used in two ways, one where the work is moving and the other where the work is stationary and the tool moves. I am leaning toward the later. In which case...

When I was young and had more time than money, I once built a thing that could be used before using that gizmo. If I had tried to purchase the thing it would have cost hundreds of dollars while the blade the thing used was just a couple of bucks. All I had to do was go at it with a dremel tool.

I should just shut-up now.

@I believe I know as well.  There is an obvious sharpened edge on the wider end (whoever has been maintaining that tool should be shot! there is no excuse for the poor blade condition).  The Double dashes on the working end are guides for grinding to desired spec.  @ Ben  The tool is movable but in two controled axis and, the object that it works on rotates on an axis orthaginal to the tools permited degrees of freedom.

Googling "Chippendale" might help if, you avoid distractions

Jeff, I don't know what you are talking about , g**gle just bring up some funny gauys 😄

No rotation involved, sorry ...  but you are rigth about the edges, they deserve a better handling, and the dashes have other causes

Next hint: windows.

I think I was headed down the same path a Jeff and may ahve been wrong. My alternative thought it was a molding scrapper used to smooth the wood after using a molding cutter.

While we are pondering what Henrik is challenging us with, I will offer the follow because "Preppers".

So Ben, is that circuit check in "the red zone" so that you can run a proper drill during simulations?

But 'readjust' the knob position, so it will point to X100 😄

If I found that gizmo in my shop, The above illstrates how I would be mis-using it.

Ben, no sorry, yours looks more like a woodturning tool.

Solution:

I have a hard time finding the correct translation for a 'Fitscheneisen' .

chisels for making grooves for hinges

It is a wood working tool, still sold

 and you use it to make a rectangular slit into a wood frame to fix a hinge with hidden fixing panels.  ?mortised hinges?

Here is a german video where it is used: https://www.youtube.com/watch?v=3cQaLbYRjD4
