The script makes no mention whatsoever of Blade having any kind of mental superpowers.
REINHARDT:
The vampire mercenary clutches Blade's sword in his hand,
but the weapon provides him with little sense of security given that
he's just seen a dozen of his men slaughtered. The automatic
sprinkler system is on now, spraying water down upon Blade and
Reinhardt alike. Blade advances.
Reinhardt's been cornered. There's nowhere else for him to run.
Refusing to be cowed, Reinhardt SCREAMS and brings the sword down at
Blade's head when WHOOSH -
But Blade swings his hands upward, slapping them on either side of the
blade, trapping the sword on its downward arc.
Reinhardt strains, trying to tear the sword away from Blade's grip.
The vampire's eyes widen in fear. And during that split-second in
which the two men are frozen, connected by the weapon which vibrates
between them, Blade says:
BLADE Tell me something, chief. Can you blush?
TWHISH! The sword twists free from Reinhardt's grasp, spinning upward
into the air. Reinhardt stumbles backwards against the blood cask
railing as --
Blade catches the sword on its way down, swinging it around in one
fluid motion, slicing Reinhardt's torso in half, along with a diagonal
axis! Reinhardt sinks to his knees as the TWO HALVES split apart,
turning to ash before they hit floor.
Beat. Blade stands beneath the spray of the overhead sprinklers,
rinsing the blood from his body. He turns towards the exit, sword in
hand.
Reinhardt appears to be terrified by Blade's martial prowess, not any sort of mental voodoo.
