Blue steel No.2 has a Rockwell rating of 63-65 HRC.
Sharpness - 4/5 Second only to premium White steel No.1 (which incidentally is poor for retention). Most carbon steels score 4 here.
Sharpening - 4/5 as easy as any premium carbon knife can be to sharpen, a knife that scores 5 here wouldn't be hard enough to be this sharp in the first place
Retention - 5/5 This is the highest score, an exceptional ability to retain sharpness
