Could a sword slice thru an anvil ?

In Wagner's opera Siegfried reforges the magic sword Nothnung and to demonstrate its power slices thru the anvil with a single blow.
If the technology such as is used for anti tank shells was applied would this be possible?

You can work out the kinetic energy of a sword, plus the arm that swings it.
You can work out the energy needed to stretch steel until it parts.
I suspect that this is far greater than the kinetic energy of the sword+arm (unless the mass of the sword imitates Thor's hammer, in the eponymous movie...).

If, however, the anvil were made out of cast iron or similar alloys, this is fairly brittle, so it may be possible to crack the anvil more easily than to cut or pierce it.

Anti-tank shells mainly use the energy stored in high explosive, applied to the target surface to direct a high-velocity plasma at the armor. This applies far more energy to the target than the kinetic energy in a sword+arm!

If the sword could emit a certain radio, magnetic frequency, in theory it could cause metal to separate much like dried mud would separate.
