I have just successfully honed my second razor and although it's only my second, I have decided to give up using the arm hair test before coming off the 1k. and use the TPT instead. My eyesight is too poor to see arm hair cut although I think I can hear and feel it.I definitely think I am improving both in my honing skills and my ability to feel the sharpness with my thumb even though it's only been two razors (two successes that is) but the difference in quality was definitely measurable.An even more comfortable shave this morning.I felt it cut into my thumb pad easier and quicker than usual even though I was still using almost no pressure. Now I know what the excitement is about honing.
