Tooth-like scales ground down into a deeply pebbled, rugged, surprisingly tough leather.
Shark skin isn't covered in scales the way fish skin is — it's covered in tiny tooth-like structures called dermal denticles, which function as natural armor on the living animal. Tanners grind these down during processing, leaving a deep, pebbled, almost wrinkled texture that's unmistakably different from any mammal hide. Most shark leather comes from blue shark, caught as an incidental part of commercial fishing and considered a less desirable catch for eating, which makes the leather trade something of a byproduct use. Every hide carries its own unique pattern of natural creasing, no two alike.
Full exotic uppers or bold overlay panels for a rugged, deep-textured look unlike any other leather on this list. It resists scuffs and scratches well and offers better natural water resistance than standard leather, on top of a reputation — dating back to its historic use as "shagreen" sandpaper — for being genuinely tough stuff.
