Mono -E Fish Knife - made of stainless steel and ebony wood finish. In the early '60s the Mono -A series was expanded with the introduction of Mono -E (ebony). The handles of Mono -E are riveted on both sides (Not Dishwasher or Microwave Safe), and the wood finish offers an attractive contrast to the stainless steel. Together with Mono -A, Mono -E and Flatware, Mono t offer the user alternatives with the same clean lines, based on personal choice.
