@Gamer_Alien: You should always have smooth shading on, if you want an edge sharp, you should mark edges as so (with the desired edge selected, 'Ctrl+E' > 'Mark Sharp') and use the 'Edge split modifier' with 'Edge Angle' unchecked and 'Sharp Edges' checked instead. When subdividing the base model into the highpoly, use…
It looks too thick to be a Terrorblade weapon, his style is very sharp and angular but those blades are so thick at the points where it should be sharp. Try to thin the edges out to give a sharper look.
I like the design. May want to change that sharp part that faces the handle; I wouldn't want to use a weapon that has a sharp blade angled towards my hand like that. One wrong move and you've impaled yourself on your own weapon.
