Coarse scratches do not create "teeth" on the apex.
Before deburring we have a ragged apex where high spots are burr and low spots are chips far wider than any given scratch.
After deburring we have a smooth apex of irregular width along the length of the edge.
There is nothing in-between that you can achieve.
To give your customers a "biting" feeling when they slice tomatoes etc, after deburring run the edge once each side on a fine ceramic - this creates a sturdy micro-burr that gives that "biting" feeling as they cut. This trick was first described by Steve Bottorff, author of the Sharpening Made Easy book.
