Ed Wusthof Dreizackwerk 9" Slicer Carbon Steel Solingen 1950s

Vintage Wusthof 9 inch carbon steel slicer made it in the 1950s most likely with hand forged after drop forged blade that was also hand ground in the old style with ebonized Fruitwood handle and brass rivets.

The curved area of the handle at the bolster Junction strongly suggest this is a postwar knife as this feature really took off then. 

this knife represent the style of knife, making done in Solingen well, skilled hand work was a crucial part of the process. Wusthof sought to remove these costly and time-consuming processes and were successful in doing so in the 1970s with their stainless steel knives that were exported in great numbers taking the wind out of the sails (and sales) of the various Sabatier brands that dominated professional kitchens. 

these old hand worked carbon steel Wusthof knives are hard to come by, they were not exported to the United States in great numbers, for everyone of these I find I seem to find 100 Henckels knives from the same period
