The flux was not cleaned out after the soldering. I have been told that the flux can be very corrosive.
That is correct. Basically, fluxes are either non-corrosive, intermediate and corrosive.
Non-corrosive is typically used in electronic applications where you don't want or can't have a trace amount of acidic material in the component. It is also used in brass and copper applications (think plumber).
Intermediate is what is termed "mildly corrosive." It's used in applications where "non-corrosive flux" isn't strong enough. It can be used to solder steel but typically test welds need to be accomplished to ensure that it capable of doing the job it's required to do.
Corrosive flux. . .is exactly that. Very very corrosive !
I was always taught to wipe down and "thoroughly clean" the areas that came in contact with "any" flux - - just in case.
Be glad that you found that when you did !
It's a shame about the other defects too !
Personally. . .doesn't matter if the maker is "non-rated, a JS or a MS". . .if they're on the market selling their wares. . .the product that they produce should be 100% ! If I'm spending my hard earned frog skins. . .I want my frog skins worth.
I don't understand the theory that the knife is a month old so no refund.

Unless there was a specific stipulation stating that there was a "specific return drop dead date."
I've met Mr. Bradshaw once. . .nice guy. . .beautiful knives (I don't have one).
I hope that everything works out for you
Raj !
