Flamberg Two-hand Swords, late 16th-Early-17th Century

[Greybeard]

Hello Michael, first of all sorry for my ignorance. I'm a collector of the Indonesian kerises which are very often wavy. While I know that the kerises were forged just this way -- wavy --, I have not the faintest idea as to how the Flambergs were made. Did they start as straight swords with the waves subsequently filed in? Regards, Heinz
