In term of particular tool, I personnaly use Inkscape for this task. 
This is probably far from optimal but it works nicely. For Inkscape < 
1.0, the following:

    inkscape --without-gui --export-area-drawing 
--export-plain-svg=output.cropped.svg input.svg

For Inkscape >= 1.0, the following:

    inkscape --export-area-drawing --export-plain-svg 
--export-filename=output.cropped.svg input.svg

or in short:

    inkscape -Dlo output.cropped.svg input.svg

I suppose there might be faster lighter tools for that and I would love 
to hear from them.

Best,
