Leather types 

Nubuck / Oily nubck – This leather is an aniline dyed leather which has been lightly abraded on the grain surface to create a velvety finish or nap. The nap is very fine because of the tight fibre structure in the grain layer. Nubuck can also be made with an oily top to give a ‘distressed’ or worn look used mainly on casual boots and shoes. The oil gives a temporary waterproofing effect until it wears off or dries out.

Pull up (also known as  – waxy or oily pull-up) This leather has had a surface finsh of a dark wax, when the leather is creased or moved the top colour lightens to give a ‘worn’ or used look.
Split suede – This is the underside of the skin , split away from the top grain, dyed and fine buffed. Suede split can be made into many different effects, from oily worn look to imitation snake or croc or simply a soft fine nap. On occasion it can be the full substance skin, buffed on the flesh side, this is usually only on calf skins as the flesh side of older animals is too coarse.

It’s lack of cover means it is the most attractive, supple and expensive leather, it also the leather which needs the most care.

Semi-analine
