Wallet from saffiano leather. Built as tester.
So far see the following pros: no need to finish this leather, surface is not exposed to scraches - very rugged, does not absorb water.
Cons: a bit more difficult in work (cutting, splitting...), looks kinda as artificial leather...
Regarding dificulty of work: I use skiving machine to split leather pieces. This machine uses ordinary razor blades for safety rasors. So I needed to replaced blades 4 times more frequently in comparisson with splitting veg tanned leather.
