From Randall Made Knives: The History of the Man and the Blades by Robert L. Gaddis, pp124-5
Quote: [During the Korean War] Another variation in the pattern of GI orders, versus those from World War II, was that now many of the knives requested were not strictly combat designs. In this dual-purpose group the Model 4 Big Game and Skinner with a 7-inch blade was far and away the most popular. This model and blade length enjoyed a considerable following among hunters at this time, plus as a large general-purpose field knife it was, and still is, an excellent choice.
In the 1948 catalog, the Model 4 Big Game and Skinner came in 5" and 7" blades. Today's Model 4 comes in 5", 6", and 7" blades of 1/4" stock. There is also a Model 4 - 4 1/2" blade of 3/16" stock. Obviously it is a lighter weight than the larger Model 4 and should be an excellent small game skinning knife. Lady and gentlemen may we please some some Model 4's. Thank you, Kevin
