Ähm, bist du dir sicher was die 59HRC bei denem Carbonstahl-Ashi angeht?
Meines Wissens nach sind bei Ashi die Shirogami-Messer alle mit 60-61HRC ausgehärtet, während die Schwedenstahl-Versionen 58-59 haben und gegen kleinen Aufpreis mit 60-61HRC erhältlich sind. Jon von JKI bietet seine "Gesshin Ginga" gebrandeten durch die Bank mit 60-61 an, da der US-Markt diese Härte bevorzugt...

Frage an Jon schrieb:Hi Jon,
The stainless knives are a little softer than the carbon steel ones. Have you sharpened then stainless ones? Any comments about sharpness maintainence with use? Is a Rockwell 58 hardness significantly different from 60-62? I have little experience with stainless Japanese knives.
Thanks,
Jan

Indeed they are a little softer. Here's how it plays out. These knives sharpen easier compared to something in the 61-62 range. Is it a huge difference? no. But i notice it. Also, they edges are less delicate. This means that these knives dont chip as much as harder ones. One other benifit is that they respond well to honing (on something like the idahone), so it makes life easier in between sharpenings (FWIW, i dont use honing rods, but i have used them and this has been my experience). For home cooks, the difference in edge longevity is negligable. Pros might notice it... but then again, its easier to bring back an edge.
At the end of the day, the difference is rather small. Depending on how you use the knife (i.e. your cutting technique) this knife may be a better fit for some. However, if your cutting like KCMA, something like the suisin or tad is a better fit. Those couple of extra degrees in HRC help the suisin or tad hold an absurdly thin angle of 3-5 degrees. However, most people will never put that kind of bevel on their knives, nor should they.
Also, Jan, all of this holds true for the stainless Konosuke knives, gelstains, MAC, and many of the other 58ish HRC knives. It seems to me that a lot of people skip over these knives just because of the low (relatively) HRC, but, as i have said before in a number of threads, they are missing out on great knives by doing so. I tell people all the time, dont chase high HRC's and Aogami Super. Instead spend some time trying to find the knife that is the best fit for you and how you cut. Consider how rough you are with the knife, what kind of cutting motions you use most, what kinds of foods you cut most, etc. and then try to pick a knife that works well in those areas.
