Can Improper Fleshing Affect the Tanning Outcome?

Importance of Fleshing

Fleshing is a crucial step in the brain tanning process, as it removes excess flesh and fat from the hide to promote even drying and prevent bacterial growth. A dull fleshing knife or improper fleshing technique can leave behind excess flesh, leading to uneven drying and a lower quality final product. It’s recommended to flesh the hide to a depth of about 1/8 inch (3-4 mm) to ensure proper removal of excess flesh and fat.

Effective Fleshing Techniques

To achieve proper fleshing, it’s essential to use a sharp fleshing knife and to follow a specific technique. Hold the knife at a 20-30 degree angle and push it away from you in a smooth, even motion. Use long, gentle strokes to remove excess flesh, working from the center of the hide outwards. This technique helps to prevent tearing and unevenness in the hide. For larger hides, it’s best to flesh in sections, working from the center outwards to maintain evenness.

Consequences of Poor Fleshing

Improper fleshing can lead to a range of problems, including uneven drying, poor hide thickness, and reduced quality of the final product. Uneven drying can cause the hide to shrink or stretch unevenly, resulting in a poor fit or a hide that is prone to cracking. Poor hide thickness can make the hide more prone to tears and punctures, reducing its overall quality and lifespan. To avoid these problems, it’s essential to take the time to flesh the hide properly and to use a sharp, well-maintained fleshing knife.
