Does the blade of a folding knife need lubrication?

Yes, the blade of a folding knife can benefit from lubrication to maintain smooth operation and prevent rust or corrosion. Lubrication helps reduce friction between the moving parts, ensuring that the knife opens and closes smoothly. It also helps protect the blade from moisture, which can lead to rust or corrosion.There are various lubricants available for knife maintenance, including dedicated knife oils, mineral oil, or even simple household lubricants like WD-40. When applying lubrication, its important to use just a small amount and distribute it evenly across the blade and pivot points. Too much lubrication can attract dirt and debris, causing the knife to become gritty or difficult to open and close.Regular cleaning and lubrication, particularly for folding knives that are exposed to outdoor elements or used in damp conditions, can help extend the life and performance of the knife. Its a good practice to periodically clean, dry, and lubricate the blade and pivot points, following the manufacturers recommendations if available.
