Video: How Much Steel Hardness Affect Honing ?

[AljuwaiedAK]

Recently a gentleman commented on honing video in my YT channel, I was honing Towa Tungsten Steel razor on A Maruoyama JNat… The person inquiry was “is it really the steel hardness or the stone cutting powers that causing the slowness”.
In that particular case, it was a combination of both, the stone has a reasonable cutting powers for a finisher, however with such hard steel and the stone surface smoothed out; the Maruoyama stone and the Nakayama slurry turned into a slow finishing combination, also the color of the base stone made it look worse than it was.




The gentleman question encouraged me to compare the hardness of different steel alloys of common razors, I didn’t pick any exotic Steels like Tamahagane, Tungsten Steel or even Swedish Carbon Steel; I intended to show that even with common European steel you can make some abrasives fail or behave differently.
In the comparison, I have used a super polished light Nakayama Asagi as base stone, and the slurry was 100% natural Saudi Pottery Clay, produced in the central region in AL Majmaah to be exact ( currently, the only information I have is that they find it 10 meters under the ground as veins ).
The razors I choose:
Henkel inox
Solingen Silver Steel
Spanish Carbon Steel “Koken by Fabricacion Española, in other word it is a cheaper version of a Fily”




This is sometimes the hidden reason behind the conflicting opinions about one type of abrasive.
