Andúril came down upon his helm. There was a flash like flame and the helm burst asunder. The orc fell with cloven head.

The shear strength of iron is 20 J/cc.
Medieval helmets were about 0.2 cm thick. 0.0143 cm in RW figures, I think.
The cut is therefore probably 0.0143 x 0.02143 x 4 = ~0.001226 cc

0.001226 x 20 = 0.02452
Mouse level

Plus the orc's skull, which we'll just assume is double the volume of the helmet.

0.001226 x 51.6 x 2 = ~ 0.1265
Supermouse level

0.02452 + 0.1265 = 0.15102
Supermouse level

This is possibly a slight underestimation, but would the blow shatter the sword?

Fragmentation figure for Damascus steel is 814.5 J/cc.
Volume of the sword is 0.0545 cc from the previous calc.
814.5 x 0.0545 = 44.39025 Human level
No, it wouldn't.
