Chef’s Arsenal is proud to offer authentic “Rotary Engraving” of this best-selling Wusthof Classic – 3 pc. Chef’s Knife Set This is different, and superior to “Laser Engraving”. Lasers can not directly engrave pure steel, so Laser engraved knives must be treated first with a chemical before “marking”. The resulting “marking” by a laser is flat, and black, and will wear off with time. Our engraving is etched directly into the steel, creating a everlasting heirloom, with your choice of text. Engraving available on Bolster only.
