TBH, a device like what I have has many combat applications. For example, I can open a portal to the pocket dimension where I store all my weapons, I could do the same (though to a different pocket dimension) as a shield, I could open a portal behind my opponent and shoot 'em in the back, it's just that I haven't found anything like it in everything I've read, so it's in my backstory rather than the weapons list.
