Thanks Dave, I hope someone has a blade by C. E. Schmachtenberg or has seen a blade by C. E. Schmachtenberg and will reply. A search on Ancestry.com does list a Carl Ernst Schmachtenberg of Solingen, however I cannot view the actual record without spending more money for European records. And it was Frederick Schmachtenberg (1822-1897) who established "Gebr. Schmachtenberg" in 1851 according to the 1907 New York State History my research found. 1851 was also the year his son, William Schmachtenberg (1851-1925) was born. William Schmachtenberg and his brother, Ewald took over their father's business in 1878. William Schmachtenberg moved to New York in 1886 to establish the New York branch and Ewald Schmachtenberg stayed in Solingen taking entire charge of the factory. William Schmachtenberg died in New York State on Nov. 26, 1925 and there is a Find A Grave memorial for him. I am also a contributor on the Find A Grave site which is the parent company of Ancestry.com
