hi KKF !
a small talk about "my" steel
as you know, i make my sanmaï myself. I use most of time the 145sc for the edge. and soft steel for the outside layers . this is not stainless.
the steel comp :
145sc :
the soft steel :
achim W, made another steel, 125sc, same as the 145sc but with "only" 1.25%c and more Mn, for oïl quenching .
the 144sc , is only for water quenching (or for thin thicknesses , with fast oïl like V35) .
