Coatings

Many blade styles have a protective coating covering most of the blade to limit the amount of care required to maintain the blade. Some of the most popular are titanium oxide, titanium nitride, Teflon, boron-carbide, and epoxy powder. Most blade coatings provide decreased reflectivity (titanium oxide and boron-carbide are exceptions) and increased protection against corrosion. Generally, the only portion of the blade which is uncoated, and thus unprotected, is the edge. Titanium nitride coatings actually increase the blade?s edge retention due to their extreme hardness.
