The "Mercator" blades were first forged in 1867 by Heinrich Kaufmann & Sohne, Indiawerk. Their reliability made them popular with Kaiser Wilhelm's Army in WWI. Eventually they garnered acclaim from civilians as well. They are virtually indestructible and have been passed down from generation to generation. Otter-Me
