Hi Paperboys,
I apologize for the late response.
Anywho, I simply used a combination of steak knife and dry wall knife, and actually a metal paint can opener.
I used the steak knife and dry wall to do the various carving of the foam, usually starting with dry wall knife. Then I take the paint can opener and randomly notch out sections of the foam.
I plan to do a video using this technique, even though there are many on Youtube.
I hope this helps!
Dave
