WebJun 10, 2024 · Generally, a knife with a Rockwell Hardness Scale rating of 58-62 will hold an edge better than a blade that has a lower HRC rating. Japanese-style knives tend to have HRC ratings of 60 and above. But steel that’s too hard can make a knife blade brittle and lower its tensile strength, so the knife will be easy to damage if misused.
