The cutting qualities are close to those of the traditional blade which oxidizes.
Stainless steel means that the blade remains shiny or mat (depends on the finish), it does not oxidize (contrary to the traditional blade.)
Sandvik stainless steel replaces the older stainless steel 440 which grinding has to be done more frequently and is more tricky to carry out.
The first stainless steel blades (until a recent period) did not have interesting cutting qualities. Rapidly those blades stopped being sharp and it was difficult to give them a correct edge back.
Nowadays with Sandvik steel it is different.
We recommend this sandvik steel because it really is a high-performance steel.
