Exactly. In the back of the book, look at the Table B, weapon 3. He calls it a falchion.
The spike on last hilt you showed does pose some questions in regards to the similarities between the two swords!

I've looked at the blade again, it does show some striations that could possible be signs of folded steel, OR just signs of cleanings throughout the years.
Some more pics.
