I found a few threads in other places that deal with building (or buying) the drag knife itself, but so far I haven't found a general solution to the drag offset issue.
Many suggestions say to just avoid radii less than some limit, or to over cut, raise re-position and start a new cut in the new direction.
They all seem unsatisfactory and don't account for undercutting on the outside of inside curves or overcutting on the outside of outside curves - - what tractor trailers do, in the US on right turns it can mess up impatient/careless bicycle riders and/or mail boxes.
So I am looking for 2D software that can DO this - i.e. handle the drag offset.
I'm supposed to say Sharks with fricki'n lazers - lets make that razors
