Otter-Messer, who has been manufacturing blades in Solingen since 1840 revived the manufacture of the Mercator pocket knife in 1995 when Heinrich Kaufmann & Sohne, Indiawerk went bankrupt. Otter-Messer, which translates to "Otter Knives," manufactured simple and strong pocket knives finished with wooden scales, all of them hand made—ground, stropped (straightened with a leather strap), and polished in their small factory. The otters who lived in the streams and brooks next the little factory inspired the both the logo and the name. Today Otter-Messer knives are fitted with C75 carbon steel blades, but the knives are still manufactured and stropped by hand. The knives are renowned for their many applications and industrial quality.
