Swords are generally pretty light. This is an absurdly big one, but it won't be that much. Let's call the blade five feet long, one foot wide, and half an inch thick. That's 46 kilos and clearly absurd.

But that's just the start. Consider that it would taper in several directions; it's not one foot wide along it's whole length, it's not half an inch through the whole thickness (it wouldn't be a sword at that point), it's not going to be half an inch down its length either.

So let's discount that triangular tip and call it a trapezoid with the other end six inches. Let's say it tapers in thickness to .1 inch at the tip (also a trapezoid), and down to zero at the edge (a diamond cross-section). This is a frustrum of a right pyramid. This gives us about 11 kilos, which is still absurdly heavy for a sword, but much more reasonable.
