Actually, what determines the price to the consumer for leather is the cosmetic appearance of the hide. It's a lot like diamonds, the fewer flaws, the more expensive it is.
The process of tanning and finishing has very little to do with price.
I was referring to water buffalo, the beast you see standing in a rice patty with a plow attached to it. They are nasty compared to cow or a real buffalo.
I've made my living selling leather for the past 15 years, so I have become a bit of a snob.
