Use Font Awesome in Inkscape
I use Inkscape primarily as my primary vector editor. I'm on a mac.
As far as I can tell, there's no way to just get the vectors directly into Inkscape (you'd think opening up the svg font file would give you something but nope)
Installed the otf font (again I'm on a Mac, if on Windows try other font types if you don't like the otf). Copy in all the characters as type.
Then "outline" them in Inkscape as you would turn any font into artwork.
This is how I got the vectors in Inkscape.
To be clear: After installing the latest Font Awesome font, I open up the Font Awesome "cheatsheet" page: http://fontawesome.io/cheatsheet/
I select the FontAwesome font as my font in Inkscape
I then copy the ICON itself from the the Font Awesome cheatsheet page and paste it into Inkscape as text.
Last, just "ungroup" the text selection until it becomes a pathed object.
You can then change/tweak the vectors.
I've added this answer to the original post as well, adding here also:
What I've done is this: create a new inkscape file with just a simple path in it. Save and close Inkscape, open the file with a text editor. Now, open the fontawsome svg file with a text editor. Copy all the tags, paste them inside the first file, inside the tag. Search for "glyph", replace with "path". Save the file. Now, open this file Inkscape. All the glyphs have now been converted to path, but they sit on top of each other.
It took me about 5 minutes of moving and resizing (align + distribute helps a lot here) to rearrange all the icons to about a dozen of columns inside a page.
You can use the "symbols" library, which is very useful.
You can import some icons, like font awesome.
