Early Robeson Cutlery Split Spring Humpback Whittler made between 1940 to 1964 "Per the tang stamp". This early Robeson D-2 Split Spring Humpback Whittler is commonly mistaken for a Queen Cutlery remake, when in reality it's one of the last True Robeson's. It Measures 3-1/8" closed and has D-2 Cutlers Tool Steel Blades with Brass Liners and Genuine Fat Sambar Stag Handles and it features beautiful Threaded Step Bolsters with the famous Pocket-Eze shield inset in the front handle. The Pocket-Eze designation was meant to signify that the blades were recessed or level with the body of the knife, as you see this is a classic example of a true Robeson Pocket-Eze Knife. This feature was first introduced by Robeson Cutlery in the late 1950's to early 1960's. The Main Blade is Tang Stamped: Robeson (Shuredge) USA "Shuredge in Script", the Pen and coping blades are both stamped "Robeson", no pattern number appearing. The Original Robeson Packaging denotes the "Pocket-Eze" designation and the model #RS47GS appears on the end of the packaging. On the face of the original Robeson packaging it says "Robeson Tool Steel". This early Pocket-Eze whittler's knife was manufactured near the end of Robeson Cutlery's business in the Perry N.Y. Location between 1959 to 1964. In 1965 Camillus Cutlery would manufacturer Robeson and ship it out of the Perry N.Y. Location until late 1970 into the first quarter of 1971 when Ontario Knife would purchase the rights to Robeson Cutlery.
