We know that razors are shaving from 12° - 23° from when we did the measurements on our razors, so if it falls inside there, life should be sweet, if not then you need to wear down the spine some too...


ps: I have never linked that vid to this forum in the past because of the negative connotation to breadknifing, so as the warning on the vid states "Use at your own risk" it is not the technique that is lacking if you can't get your razor sharp again it is your skillset....
