Not sure why you think that knife (that you posted in the other comment) is substantially safer than a regular knife. It’s similar to wavy-style bread knives, but smaller. The edge of the blade is still extremely sharp and reviewers have even noted they’ve cut themselves with it. The bread knife I own can easily cut me and it basically is just a larger version of what you linked with larger “waves”.

I don’t know how you could possibly mince herbs or dice vegetables into small cubes with something like that knife though. You need the flat slicing motion. Interrupted cutting like a bread knife does will lead to very messy cuts.
