Goddammit. ...Okay, I found a formula on the internet with which one can calculate how much force one would need to punch through a metal, I have no idea how reliable this formula is with rocks.

F = πd x t x σ

with F as the force in pounds, π as Pi (so 3.1416...), d as the diameter of the punch, t as the thickness of the material and σ as the material sheer strenghth.

I have no idea how helpful that is.
