Full-Grain and Top-Grain Versus Split Leather. The typical leather hide is split into two parts. The surface layer, the layer closest to the animalâs hair, is called the top-grain layer. The lower layer is called the split layer. In our industry, full-grain leathers, which include both layers, are the most desirable. The natural markings on the hide are attractive, and so it is not necessary to correct the surface appearance of the leather in any artificial manner. Top-grain leather is slightly less desirable.

From Wikipedia, the free encyclopedia. The hectare (/ËhÉktÉÉr/ or /ËhÉktÉr/ ; symbol ha) is an SI accepted metric system unit of area equal to 100 ares (10,000 m 2) and primarily used in the measurement of land. An acre is about 0.4047 hectare and one hectare contains about 2.47 acres. In 1795, when the metric system was introduced, the are was defined as 100 square metres and the hectare ( hecto-  + are) was thus 100 ares or 1â100 km 2. When the metric system was further rationalised in 1960, resulting in the International System of Units (SI), the are was not included as a recognised unit.
