Abstract
The present invention relates to a razor blade having one or more coatings formed by the atomic layer deposition (ALD) process, the formed coatings being uniform, conformal, and dense. The coatings may be on an entire surface of a blade flank, and at least a portion or an entire surface of a blade body. The coatings may be etched. The invention relates to a razor blade having a first coating of a first material and a second coating of a second material where at least one of the first and second coatings is deposited using an ALD process and the second coating is deposited on a top surface of the first coating. The first and second materials may be similar or different. The present invention relates to a razor component having one coating of at least one layer of one or more materials formed using an ALD process.
