Easier Way to Cut Edges in Cubes?

I used Booleans and planes to cut the edges of this cube, but was wondering if there was an easier way to do this?

try with bisect !
or knife cut

happy bl

There was a tutorial on Blendernation.com not too long ago that uses the bisect tool to create shapes/rocks like that:

Thanks Ricki the Bisect tool is just what I needed.

Thanks dunawayc, watched that video alredy. Its a good one.

There is also a sculpt add-on that uses the grease pencil to cut pieces out of objects.
