Copper will cause the steel to corrode faster, as it is a sacrificial anode....


however, for that you'll need an electrolyte, ie, salt water, and it to be soaked in that stuff constantly.

in which case, your knife is fucked anyway.

pic sort of related, a 500-year old knife from the river Thames. copper/brass is still fresh, steel is pretty beaten up.

However, that's after 500 years in a river. I dont think you need to worry about it corroding the steel, in a dry leather sheath, in your lifetime.
