This type of rasp is also known as a 'float' with either straight cut or curved (MILLENCUT) teeth
I suppose it is a float, though I associate floats with the plane makers' tool for working the throats of wooden planes.
With the handle system, it's an auto body tool, certainly. The toothing is found on lead working tools. But like the
plane makers floats I know, these are very good for working wood. I have several and wouldn't be without them.
They can take away a lot of material, and since they are like having a bunch of little plane blades, they leave
behind a very smooth surface.
