Unobtanium I am guessing?
Problem is 2" diameter is squat for strength when trying to use it as a handle for a 1-2 ton weight ...
... plus the acceleration and the impact.
Ludicrous.
here is why:
Iron has a shear modulus of 82 GPa, Tungsten 161 GPa.
Basically that means if iron can't handle a 500# load then Tungsten won't handle a 1000# load.
Hickory runs 14.8MPa for shear or roughly 0.0146GPa IIRC. That would put tungsten at maybe x10,000 of Hickory which means it SHOUL handle the shear, but Hickory has a MOE of 15.583 GPa as well although Tungsten is probably only running at 411 GPa which puts Tungsten at only 30x more resistant than Hickory and thus the 1000#-3000# head severely questionable compared to a 3#-6# sledge with a 2" diam hickory handle (aka, it may handle the shear, but there are other stresses involved as well).
Dresden is able to pull off what he does by obeying the laws of physics. These include things like shear strength and exploiting the weakest (or least protected) points.
