Thank you, folks -
Mario, the damascus on a suji is a half-brother of yours and Rick's gyuto steel.
These blanks haven't been heat treated yet, so they don't show right colors (Spirograph will be dark after HT)
Machine finish I am aiming at is similar to Bob Kramer finish of his 52100 custom knives.
These are profiles you will see on my knives. They are derived from Masamoto gyuto, but are not 1:1 copy. There are two notable differences with Masamoto that will put them apart in terms of durability and performance.
