Blades, i think cutco uses 440b. based on my non scientific testing, and regular use, i consider 440b, 420hc, 8cr13, aus8, x50, 4116 krupp, and probably 440a as all similar enough that i would not be able to tell the difference in actual use; without side by side testing., the thing about Case is they are also Ka-Bar, and Cutcosame company, same plant, same quality control, same warranty, same customer service I have never had a problem with any of my newer Cases.
