I don't know where Felco or Bahco (previously Sandvik) are made, but my Japanese Okatsune hand pruners have a Rockwell hardness of 70, noticably superior to all others I've used.
With Japanese handsaw blades, the Silky tool steel is certainly better than Corona, as well, the machining process is likely better. Corona blades often seem a bit rough. But then there is the impusle hardening procedure to consider.
