Have you checked the descriptipn? I think it is an arrow, with the associated issues, not a hand weapon you hold onto.

Subject: Drop Weapon Magic Item?
A magic weapon with “Drop Weapon” (power 1 or 2) seems to be a very cost-effective upgrade. It costs only $500 and seems to me much better than getting +1 damage or +1 DX from getting a Fine weapon made (which would cost a similar amount or more for most weapons). Granted I may be interpreting the rules incorrectly - my impression is that there is no ST cost to ‘power’ this spell. A warrior equipped with this magic item simply hits their enemy with the weapon and they are guaranteed to drop their weapons and shields.
