Good to be in touch with you again!
There is a considerable amount of ‘Sheffield’ cutlery which is
manufactured overseas. That said, the main issue is usually the
grade of stainless steel that is being used and the chemical
treatments that some manufacturers give it to try to reduce nickel
release. There is an excellent organisation based in Sheffield called
CATRA (Cutlery and Allied Trades Research Association;

with much more specific as they now function as an
independent testing laboratory for many major UK retailers.
