If it didn’t occur to anyone, this might be helpful.
Rather than engrave the entire “block” around the stamp like this(which would take FOREVER and dirty up the inside like crazy)
I created a selection around the stamp - including the slope gradient - and filled it with black
Then I saved that just black and white image in the same dimensions as the stamp and took it into Illustrator to do a Live Trace/Paint thing and expanded it to create the cut line
This way it engraved only the minimum amount of material and I didn’t have to trim any of the stamp with a razor by hand afterwards
