Knife Steel, Böhler M390 and the Benchmade Nakamura 484
Old Man Metal focuses on folding blades with a knife review of the Benchmade Nakamura 484S and the Böhler M390 stainless steel used for the blade on the third episode of his solo podcast, taking a deep dive into stainless steels, particularly modern powder metallugy “super steels”, including an in-depth look at heat treatment, tempering, and the elemental composition of stainless steels and the effect those elements have on hardness, strength, toughness and corrosion resistance… all while drinking an Old Tuffy lager show beer from New Belgium.
