Whereas others insist that it is all Sodium Chloride

It's about the source, method of production and texture.
Flakey sea salt is nice and fluffy, not very abrasive.
Rock salt (mined from underground and ground up into chunks) tends to be much denser and thus much rougher and more abrasive.
When choosing salt for duck skin rubbage I would go for the fluffy stuff rather than the dense stuff as it's gonna tear the skin far less so you end up with a much less tatty result. Also, being less dense than rock salt you'll end up
using far less salt so healthier. That's also why I advocate use of a very sharp fork for skin piercing, rather than just any old blunt shite from your cutlery drawer.
Sure, rock salt has it's place, but not here.
