What the Dilucut does it pretty interesting though.
You hone without tape, set the bevel, so the original bevel angle that the razor was made with remains the same. Add a layer of tape to create the secondary micro bevel. Once that doesn't cut it anymore, you remove tape, re-create the primary bevel which remains the same angle as original; then you can re-add tape for the secondary bevel and skip a big part in the refining of the edge.
Some people seem allergic to wanting to change the original bevel angle of the edge that was put on the razor in the factory and don't like adding tape. There are upper and lower limits that do matter to make the razor shave well. It can be calculated.
Some won't hone without it.
I don't really care much, you do you, as long as the angles are within proper shaving angles, all is well. Tape or no tape.
