Hello Samuel and Michael,
interesting discussion
the Sabre (Russian Sabla, polish szabla, Magyar's szablya) probably has been imported from the south of Russia to Europe also parallel there were obviously influences from the orient.(re;Attila's sword 850-950 Weltliche schatzkammer Vienna.)
the definition of the sabre is; a sidearm with a long curved blade and a asymmetric grip often bent towards the forward quillon, which has no pommel as a sword but can have a pommel cap instead. (Heribert Seitz Blankwaffen 1
p 183).
if we use this definition on Michaels sword/sabre, it is not a sabre because of it's straight grip and hilt.
Seitz also mentions that in the 16 Century the sword makers in Graz and Passau hat the expression DEUTSCHGEFASSTE SAEBEL/ GERMAN HILTED SABRE for a type of sword with curved blade and hilts with pommel. Also the swiss Sabre is part of this group.
this statement makes Michaels sword, belonging to this group, a sabre
regards from Holland
