The other knife with the jigged handles is an old stock Schrade USA 708 1973-2004.
The shield is a bit larger on the black handled knife and it does not say Schrade...the tang is the same Schrade USA 708. There is one diference I just noticed there is a cross to the right of the Schrade on the black knife.
Bryan lists a Sag 708 with the Federal shield 1946-1956.
Really my question is is this knife 1946-1956 or is it a 708B 1973-2004 or something inbetween?
