There are vertical cloth shutters - my Leica CL for example. Also very old
large format reflex - see the classic shot by Lartigue of the race car for
the distortion effect.
All the metal multi-blade shutters create a slit too at high speeds -
highest flash sync is simply the highest speed at which the shutter is
totally open for ANY time. EOS 620 was 1/250th (double the speed of other
contemporary and later models) and they get a good price still for that
reason.
