Just to be fussy, the photos posted of Turk bayonets are of the 1935 reworked, ten-inch blades. The original Turkish 1903 blades were "quillback" like the German S98, and featured a stiffening rib like the shaft of a feather in addition to the fuller, with part of the blade edge protruding above that shaft like a dorsal fin on the latter third of the blade. That tip shape might, interpretively, tie in with the diamond-shaped tip on the dagger you posted.
