El Unico Orange Knife

This advertisement from The Century magazine from 1894 shows another Victorian way of dealing with the orange.  The knife is steel and is silver plated. The handle is sold in ivory, pearl, celluloid, sterling and silverplate. It "has a fine saw edge" and can "cut orange and grapefruit smoothly without releasing any bitter oils from the skin".

Other than this advertisement I have never heard of El Unico of St. Augustine Florida. Rainwater nor any other of my references mention this maker. It is possible that they are a reseller. However, te blade is stamped with their mark. To be honest again if someone brought me this knife I would probably confuse it with a cheese knife which it closely resembles.
