7. Durability of leather
Raw leather is extremely durable, with full-grain leather being the most durable since the animal hide’s epidermis is intact. However, the more important question is the durability of the leather product on a whole. It is broken into two aspects:
- Functional durability
- Aesthetic durability
A worn out leather belt strap best explains the two aspects above. A leather belt strap is functionally durable because it easily lasts for 10 years without tearing into halves. However the belt strap would cease to look desirable by then, ie the functional durability has outlasted its aesthetic durability.
