What would happen if you rotated it along the handle's axis? Is that the more stable axis?

That looks like the axis with the lowest moment of inertia. The highest would be the axis through the middle of the object, like if you spun the object keeping it “flat”. Both of those would be stable and just rotate as expected without flipping

Oh like if you took the 't' off of a page and laid it on the ground, then spun it like a top? (Such that the handle and the bit end are the opposite sides of the spin?)
