Vintage Wusthof 6 inch carbon steel flexible slicer made in approximately the 1950s with hand forged after drop forged blade that was also hand ground in the old style with walnut or fruitwood handle and brass pin and disc rivets.

Highly flexible blade is very full, it has a fresh edge on a very full, non sharpened down blade. One disc of the pin and disc rivets is missing. 

This knife represent the style of knife-making done in Solingen when 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.
