Leathers come in a wide variety of finishes
The preferred method for adding color to leather using non-toxic aniline dyes. This translucent dye does not conceal markings that are part of the natural beauty of leather.
The process by which leather is made to appear aged. Usually done by hand, using techniques such as lubrication and sanding as well as hand staining with aniline dyes.
After deliming the leather, enzymes are used to add softness and flexibility to the hides.
Full grain leather will breathe and adjust to temperature.
Process for correcting leather and eliminating natural imperfections in the grain. Often times light sanding is performed, after which a more consistent grain is embossed on the leather. Buffing is also used to remove the grain to create nubuck or suede.
A tanning process chromium sulfate and other salts of chromium, producing a more supple leather than vegetable tanning.
Leather tanned with multiple tanning agents, usually a combination of chrome and vegetable tanning, combining the benefits of both.
Leather in which the surface has been sanded, or buffed to remove imperfections, then micro-pigmented and embossed with a more uniform grain texture.
Leather that has been treated to age the appearance.
Eight-Way Hand Tied Coils
Heavy gauge coils which are individually tied to one another from front to back, side to side and diagonally (eight ways) to provide a high level of quality, comfort and durability. An expensive process that can only be done by hand.
The process of applying an artificial uniform grain to the surface of leather after imperfections have been lightly sanded, or buffed out.
Application of any number of effects to leather after tanning, such as aniline dyeing, buffing, embossing, antiquing, distressing, etc.
Leather which gains all of its color from being tumbled and soaked in large stainless drums with translucent aniline dyes.
Full Top Grain
Considered the best, this is leather which has been aniline dyed, but has not been mechanically altered. Natural characteristics and markings such as scars, barbed wire marks, and wrinkles are left intact and are considered to be what adds character and beauty to premium leather.
