Understanding Whetstone Sharpening
Before we dive into the water vs oil debate, it’s essential to understand the basics of whetstone sharpening. A whetstone is a flat, rectangular stone used to sharpen and hone the edges of knives, scissors, and other blades. The stone is typically made from a abrasive material, such as silicon carbide or aluminum oxide, which wears away the metal as the blade is stroked across its surface. The sharpening process involves drawing the blade across the stone at a specific angle, using a consistent motion to remove metal and create a sharp edge.
The Role of Lubrication in Whetstone Sharpening
Lubrication plays a critical role in the whetstone sharpening process, as it helps to reduce friction between the blade and the stone. This reduction in friction allows for a smoother sharpening motion, preventing the stone from loading up with metal particles and reducing the risk of scratching or damaging the blade. Lubrication also helps to prevent overheating, which can occur when the blade is subjected to excessive friction. Overheating can cause the metal to become brittle, leading to a dull or uneven edge.
