does anyone know the difference between the different types of leather?

  1. Hi. I was wondering if anyone knows the difference between the different types of leather available on purses? For instance, other than the type of animal it comes from, is there any difference in quality between say, leather from sheep skin versus buffalo leather? Is one type more expensive or durable than the others? I obviously know that exotic leathers such as alligator or ostrich are extremely expensive and rare, but was wondering about the more basic leathers.
     
  2. YSL bags are sometimes made of buffalo, and it seems to be lightweight, yet durable and scratch resistant. I've really like the ones I've had.
