Thank you so much for your review and for sharing your experience. We’re so glad to hear you’re enjoying your Henckels Elan set, though we’re sorry to learn that your paring knife developed a rust spot. Our knives are made from high-quality stainless steel designed to resist corrosion, but occasional rusting can occur if moisture remains on the blade. We recommend washing the knives by hand, drying them immediately after use, and storing them in a dry place to help prevent this. If the spot persists or you’d like us to take a closer look, please don’t hesitate to contact our customer service team at hello@henckels.com, we’ll be happy to help.
