This morning I decided to refresh the edge of my Dovo half hollow using a Belgian Blue. I have had good results using this stone with a full hollow Dovo but today the half seemed dull. Anyway, I took the full hollow from its storage and wiped the oil off the blade, then gave both razors 30/60 felt/leather and shaved with both. Using the half hollow I shaved the left side with my left (non dominant) hand and vice versa with the full hollow. The half hollow, despite not appearing as sharp to TPT, was clearly the better shaver. Maybe its just confirmation that the only real test is the shave.
