The camellia oil included in the set is food-safe and free from paraffins. Camellia oil is derived from the seeds of the camellia tree, which originates from East Asia. Centuries ago, the oil was used to care for valuable sword blades. Today, it primarily maintains high-quality knife blades. Especially for non-stainless knives, the care oil provides additional protection for the surface against corrosion. Regular application is recommended. Additionally, faded knife handles can also benefit from the care of camellia oil.
