If you're going for a semblance idea, i  would suggest either solid-light projections on one handle, or, if it's the Semblance that's controlling it, then I think something similar to the cube idea may work. if, for example, the person wore a thick segmented bracelet, then he/she could use telekinesis to disassemble said bracelet and lock it into the shape of a small sheild, a sword, or a gun. t he way you described the cubes, though, is completely impossible.

Phantom? thoughts?
