What the name describes
Nappa is a finishing method rather than an animal or a grade: full-grain hide, usually lamb or calf, chrome-tanned and dressed to stay soft and elastic. The grain layer is kept intact — it is not sanded off and reprinted, as it is on corrected-grain leather — so the surface keeps its natural pattern and gains a patina instead of flaking.
In short
- Type: soft full-grain leather, tanned to stay supple
- Why for cases: folds daily without cracking; ages rather than wears out
- Not: bonded, coated or corrected-grain leather, which crack at the fold
How to tell
Press the surface with a thumbnail. Full-grain marks lightly and recovers. Coated leather resists, then creases permanently.
The part people get wrong
A good case is not a drying cabinet. Leather absorbs and holds moisture, so an instrument put away damp sits in a humid pocket for days — the most common cause of spotting on otherwise well-kept stainless. Dry the instruments, then close the case.
Care
Away from sun and heat, conditioned once or twice a year with a neutral cream. Water marks usually fade; heat damage does not.
Instruments where this matters
Questions we get
Is nappa the same as full-grain?
Nappa is a way of tanning and finishing full-grain hide to stay soft. All nappa worth the name is full-grain; not all full-grain is nappa.
Will a leather case protect instruments from rust?
No — it will cause it if you put them away wet. Leather holds moisture. Dry the instruments first, and leave the case open after use.
How do I look after it?
Keep it out of direct sun and away from radiators, and treat it once or twice a year with a neutral leather conditioner.

The cutting head of a nipper, measured in millimetres or as a fraction. The longer the jaw, the more it removes per cut — and the less forgiving it is.
A German martensitic stainless steel used for grooming and surgical instruments — hard enough to take a fine edge, stable enough to resist rust.
A file whose abrasive is etched into tempered glass rather than glued on. It sheds no grit, washes clean, and keeps its cut for years.
A bevel ground as a curve rather than a flat facet. It puts more steel behind the very edge, which is why fine points survive on convex-ground blades.
