Rockwell Hardness (HRC) & Edge Life Estimator

Drag the Rockwell slider from 52 to 64 HRC to simulate blade edge retention, micro-chipping tendencies, and see which real-world knife steels match that hardness profile.

Adjust Rockwell Hardness (HRC):

61HRC

52 HRC (Soft Monosteel)58 HRC (German Steel)60-62 HRC (VG-10 Damascus)64 HRC (SG2 Super Steel)

Optimal Bevel Angle:

12° - 14° per side

Metallurgist Note: The global gold standard for Damascus cutlery. Glides through delicate proteins with zero resistance.
