Vintage / Antique J A Henckels (no model number) carbon steel French style flexible slicer, hand forged after drop forged and hand ground carbon steel with French style cuisine massive / Nogent style handle. 
 Thin light and super nimble, this is from when Henckels was at the top of their game quality wise and shows the wide influence from French knives in professional cutlery.  
 Blade is very full and free from abuse, the bolster was ground off from the heel altering its original design but it is not badly done or distracting in my opinion. There is a tight crack at the heel that is very stable but there.

 9" blade, 14 7/8" overall length 3.7 oz
