your knife is a copy. At first the arrow on the head is bad for SMF manufacturer. This arrow on head was used for Weyersberg. Then the logo SMF was used on second type gravity knife only post war and was etched by acid. Your blade has logo SMF stamped as I can see from photos. Then the shape of acceptance stamp on the spike is wrong. This shape of eagle was not used for gravity knives during the war. Next the spring looks even repaired. I can write more signs what confirm that is a copy, but I think these i wrote are enough ;-)
So this knife you posted here is not period original ww2 gravity knife type 2 !!!
