You dont have to wield the wand of shield to use it?? Well, that seems strange, but cool.
You have to wield the wand to cast the spell initially, but then you can just stow it away and the spell keeps going for its minute/level duration. The way a ring of force shield works, you have to have one hand wielding the wall-of-force-shield at all times to keep the bonus.

Unfortunately, shield bonuses don't stack with each other. It's probably good to have both, though, since you can cast shield from the wand if you're expecting a fight, but still have the arcana as a backup in case something catches you unprepared.
kk
the arcana is also a bigg investment there is arcana's wich giva alot better things if you get wand wielder arcana you can use wands in spell combat and dont provoke aoo
and its only 750g for a wand of shield cl1 wich last a minute so the whole combat! the wand wielder arcana also les you cast other wands as part of spellcombat like a wand of vanish or shocking grasp
