Full grain, top grain, split: what the grading terms actually mean

Leather Knowledge — Materials Desk

Most leather labels on the market tell you about the animal. Very few tell you about the layer. The layer is the part that decides whether the piece improves or flakes in five years.

hide anatomy

A hide has three layers and only one of them is worth keeping

Every hide arrives as a single piece of skin roughly a metre and a half across. The cross-section splits into a papery top layer, a dense middle, and a flesh-side split underneath. A tannery sands the top layer down by fractions of a millimetre to reach the colour and firmness we want.

  • Full grain: the unsanded surface. Marks, pores and healed scars are still in it. This is the strongest, most expensive layer and the only one that keeps developing a surface.
  • Top grain: full grain that has been lightly sanded or embossed to even out colour or add texture. Still excellent. Slightly less fibre, so it scuffs more evenly instead of tearing.
  • Split and corrected grain: the flesh-side split, coated in a pigmented layer to imitate the top. It looks like leather for about two years and then the coating is the surface you actually own.
what 'genuine' tells you

“Genuine leather” is a floor, not a ceiling

On a label, the word genuine only has to mean that the material is not synthetic. Corrected-grain split leather qualifies. So does a very thin bonded offcut. It is a legal threshold designed to stop people calling plastic leather, and it is not a quality signal.

If you want a meaningful term, look for full grain or vegetable-tanned, and ask what the tannery is. Both are checkable. A brand that answers precisely is a brand that has looked at its own stock.

Ask what the tannery is. It is the only material question with a real answer behind it.

what we buy

One grade, one tannery, one thickness

We buy full-grain vegetable-tanned hides from a single tannery, at a thickness that lets us skive edges without punching through. Keeping the specification narrow is how a small workshop keeps quality consistent without a large staff.

  • Full grain only, unsanded and unsplit.
  • A single named tannery, visited in person at least twice a year.
  • Thickness chosen per piece so edge finishing can be burnished rather than painted.
