The sword page lists the Wrench Wand's attack style as a unique style ("wand"), but it seems very similar to a Spur.

So, should it be listed as a Spur, or does it have enough differences to keep being considered a unique attack style?
(Also, only charge projectiles were tested, and I used a level 10 Arc Razor for the Spur info.)

(I tested all the things mentioned here with the Wrench Wand on Ironclaw Menders, hitting them with their own weapons.)
Its regular attack pattern follows Calibur and Brandish attacks, not Spurs. Additionally, its projectile is extremely unique, fast-moving, and has odd "pulling" knockback, while Spur's is more random as well as slower. Spur's also focuses on "slicing" the projectile, while Wrench Wand's projectile is "cast" from the wand.
It's its own weapon by any right.
