Eftihis,
The blade on your sword is exemplary of the type usually found on Swiss sabers, backedge included. This link will take you to the only image of a Swiss saber I could find online-- it is the bottom one.*

Please note that there are a variety of different forms of hilts and blades to Swiss sabers, this is just one. However yours falls well within the realm of its type.
The Italian saber to which North attributes the Nimcha's form is shown in
Sword and Hilt Weapons, Coe et al, p. 77 left.
Sincerely,
Ham
