And you should!
Note you are completely incorrect in your assertions here. I do enjoy reading the lounge from time to time and as a person who spends an inordinate amount of time in tanneries working with owners and buying drumloads of leather I will say this is nonsense. I can't speak for other companies ordering from distributors but we visit our tanneries on a regular basis and meet with the staff, owners and other team members. Im curious if you have any expertise at tanning, running a tannery, working in a tannery or making leather jackets? If you ever have questions about information on our website you are welcome to drop a line and grab clarification. Regarding my team of sewer/cutters we go over every load of leather received and determine colour consistency condition etc...I mean why write this post at all ...I happen to have spent plenty of time at both McCoys and the mfg for Finecreek and I will tell you this is offbase and factually incorrect.
The only leather experts are the people working at the tannery. Leather jacket makers are tailors & designers and they certainly ain't tanning experts. They'd be waaay better off just saying "This is our brown leather and this is our black leather. They're all pretty cool!" 'cause frankly, at this point, that's all I wanna know.
Believe me, the only thing that makes sense is to forget 90% of "terminology" you hear getting thrown around out and just focus on color, texture and thickness (though even that part is filled with bs).
What @Jin431 says, it's just marketing techno-babble. Process of tanning is very complicated & by the time any information on how a batch of leather that some specific maker sourced has been tanned, gets transformed into a blurb on some retail platform, it went through so many levels of misunderstanding that it's best to simply ignore it.
I mean, retail websites can't even tell the difference between leather that's been split into layers & leather that a machinist flips upside-down before starting working on a jacket. Most of the internet believes Shinki is a type of leather!
What's happening is that you're hearing all of these terms from people who've never set foot into a tannery. For instance, read the descriptions on Himel's "about our leathers" page - You'll notice that all "descriptions" consist of the exact same terms that have been slightly rearranged. They can't even get the suede bit right!
But that is okay!
Because leather jacket makers themselves aren't even sure what they're buying and will for the most part just source leather that's got all the characteristics their product is known for; ie. what they're used to working with and ultimately, what the consumer expects from them.
It often happens to the tannery that they run out of a certain type of leather, which then forces makers to look for the closest match. I mean, that won't happen to Fine Creek or Real McCoy but it happens. It happened to Schott and Vanson. But what I'm getting at, not even the machinists will notice something's changed, let alone people who talk about tanning on social platforms.
People who have been in the industry for decades will happily tell you they don't care how the leather has been tanned as long as it checks all the boxes they require and I do believe that's actually a very healthy approach to all of this.
