As you can see in this threat it is really hard to comment on hand made knives
Some will be harder then others, they are not all the same, i have sometime had Shig that was softer then Yoshi and visa versa.
Also seen some blue steel that take better edge then white. its really hard to comment on those steels or knives when they are fully handmade. They all have some variations and always will have.
In general i think that Shig take better edge then V2 or any Yoshikane knives but only in General
