Every culinary connoisseur owns a sturdy set of kitchen knives, and they put a great deal of work into keeping these knives sharpened at all times. But you can put your worries aside with Furtif Evercut Knives. The laser-bonded titanium-carbide surface lasts 300 times longer than standard steel, meaning you would only need to sharpen it once every 25 years. Not 25 days, not 25 months but 25 years. Call it Excalibur?
