Suitable for industrial and medical applications, 400 series martensitic
steel is much more corrosion-resistant than carbon steel and can be
sharpened to equally-keen edge sharpness. Specialty Blades maintains
an extensive inventory of Razor Blade Stainless steel in thicknesses
from .010”-.062” thick, as well as 420 “Cutlery Grade” Stainless
steel.
