They're similar in design to a Falchion so in theory you could get away with calling them as such though a Falchion tends to have a longer more curved blade.

I would also note that you should if writing pure fantasy/fiction avoid using the proper names of any type of sword excluding perhaps the Broad Sword or Long Sword and Short Sword. The reason for this is unless your world is based heavily on the existing countries/world then your nations are not likely to be speaking Greek, Spanish, French, Japanese, Hindi etc to get these names. A good writer would generate his own names representative of the language of their home fantasy country and culture and merely use an accurate description of the swords in question to describe the blade type. Of course, that would take a lot longer and far more effort to do but if seriously interested in writing sci-fi/fantasy fiction that comes with the territory, learning that even simple things such as air, water, earth, fire can need a whole different word to explain them. When the 4 base elements require new names for different cultures and nations not found on this earth, then imagine what something as complex as a sword would need.
