The plated smooth handle mark 2’s are all post War parts knives made by the Weske Co. in Sandusky Ohio. They bought the Parts from Ka-Bar and made commercial knives with them from 1946-1952. Camillus did make a plated blade Mark 2 but Ii had the standard 5 groove stacked leather washer handle. I always liked the early 1943 blued blades Ka-Bars. At one time I owned both Robeson USMC Mark 2’s shown in Mike Silvey’s WWII book. My personal favorite WWII knife was the Case 7” double edged Stilettos issued for quite dispatching. The extra long leather sheath was issued for this knife with troops wearing Parka’s. I have an example that was worn by a member of the 10th mountain division. I can post pics when I get back from South Haven. Get back Fathers Day.
