Glove of Division

Slope Dude 4
A creation out of the pure might of the Math Titans, the Glove of Division is forged and fitted into the hand of Slope Dude upon gazing his eyes upon the infinite and vast knowledge of Mathematics I. The Glove of Division can divide the population of the universe in 2 using the division square in the middle of the glove. The Glove of Division is then stolen by Thanos Dude and he says undefined, thus the world's population is cut in half.

Beyond
The Glove of Division lives on, bleeding through another reality, to embark upon another user to bear it's dividing abilities.
