 That is a Big Sword! 

I can find very little about the actual weapon in the display case. Usually in folklore, the sword has a history
that hints of magic and reliance. For many of my young years, I thought the above sword was called 'The Falchion'
and didn't consider the moniker as a style of weapon.

Maybe others could shed some light on the type of sword?

Yessir, it's a falchion of sorts in all particulars other than the back of the blade.

In his epic tome "A Glossary of the Construction, Decoration, and Use of Arms and Armor in All Countries and in All Times Together with Some Closely Related Subjects", George Cameron Stone has this to say of the falchion:

FALCHION, FAUCHION. A sword of the Middle Ages. We have no very positive knowledge of it, but it is usually represented with a broad curved blade widest near the point, and in which the back joins the edge in a concave curve. (Planche 184).

So the sword in question qualified generally as a falchion, with the exception of having a straight rather than curved back to the blade. However, back in the days when all weaponry was hand-forged, multitudes of variants occurred in each and every weapon type, as befit the whims of the maker, so I would not consider that detail to ban it from the ranks of falchionry.

The blade is shaped much like  many modern-day machetes, and so I would think it to be just the ticket for chopping and lopping off the head of a wayward Wyvern, and disassembling it's body to be tossed into any nearby convenient river.
