Leather Knowledge - Sokoto

Genuine Sokoto


This is a picture of most recent Sokoto - showing grain - the lines or what some call "rivers" are very prominent in this sample . The grain was not mechanically manipulated.- The tannage brings out the grain. As skins are very individualistic, the grain prominence will vary from skin to skin



Counterfeit Sokoto



Purchased by a straw buyer for our input. This is sold as Sokoto. It is not.


The grain has a bad break, loose grain, as the result of excess mechanical manipulation trying to emulate the grain of genuine Sokoto







How important is the grain when purchasing this leather?


Unscrupulous manufacturers employ numerous methods to counterfeit the distinctive grain of genuine Sokoto leather. The essential fact is this: counterfeit Sokoto is produced through manipulation that weakens the grain–corium interface, undermining the integrity of the material.



Companies accustomed to producing shoe leather, routinely tanned with chrome and other industrial agents, fail to grasp a fundamental truth: leather intended for bookbinding cannot be considered historic or archival if it has been processed with chrome or similar substances. Shoe leather may suffice for covering the sole of a foot, but it bears no relation to the standards required of true bookbinding leather—crafted to preserve, protect, and comfort the soul of the text itself.
