Teoretically it could be inspired by PS1853/62 austrian pioneer sabre.
I think Andy is right, probably Austrian or German Faschinenmesser ?
French M1831 cited as a source model for all subsequent similar pioneer swords.
In short, I wanted to tell that the PS1853/62 austrian pioneer saber, mentioned by Andy, also modeled on the French M1831.
If I'm not mistaken the French Mle 1831 short sword did not have saw teeth on either side, and had a solid brass grip like the one pictured below. Said short sword more or less exactly copied by the Russians as their pattern 1848 r (goda) infantry troopers short sword - but not before they manufactured the pattern 1834 r (goda) French 1831 style hilt for their pioneer's short sword that did have saw teeth on the backside with a slightly curved tip at the pointed end of the blade. With the possibility of Austria not a bad idea IMO with sawbacks there being made at least from the 1760's, although by 1862 the teeth seem to have been omitted? With the preceding Faschinenmesser of 1857(?) uncertain as to the saw teeth, but having a somewhat similar shaped grip. And with all that said, this one is new to me with my best guess at the moment perhaps being something like a higher grade (more decorative) private purchase sword? PS: Has the blade been shortened? Best Regards, Fred
The blade is too short for the scabbard, most probably shortened blade, the design of handle is near of PS1853/62 which is certiainly different to french FM1831.
