Step 1: Understanding Snuffing on Grain
- Snuffing refers to a process where the surface of the leather is lightly brushed, creating a velvety nap or fuzzy texture on the grain side. This soft, brushed finish is characteristic of Nubuck leather.
- Nubuck is made by sanding or buffing the grain side of leather, which gives it its distinct velvety feel.
- In contrast, Suede leather is produced from the flesh side of the hide and has a softer texture but is not made by snuffing.
- Full grain leather retains its natural texture without sanding or alteration, and oil finish is a type of treatment for waterproofing.
Step 2: Conclusion
Thus, the correct answer is (A) Nubuck, as it is the leather produced by snuffing the grain.
