sword stick, unusual blade type

[fernando]

Hello, could somebody help?
The attached are magnified pictures of a concealled blade mounted on a sword cane that i bought at first site.
The weapon as a whole, despite the reasonably well carved handle, looks to me an uninspiring mix up of vintage to modern components, and i have no hopes about its colecteable interest.
However, this is the first time i see this type of blade ... a slim 5/16" wide sort of estoc , with a "false" triangular section, like a concave sided V.
I wonder if this some fantasy arranged by the guy who mounted the whole thing, just to sell it out, or if this is a real tipifyeable blade.
Thanks for your coments.
.. and so sorry for the imense space used with the pictures.

Maybe a bayonet section?

This cross section is not uncommon on sword sticks from various parts of Europe, and even Britain. I don't have an example in my collection (not that I have many sword sticks) but I've certainly seen them from time to time.

This hollow triangular crossection is very common to see in 19th c. "duelling swords" and 18th-19th c. smallswords. As examples of the later:

Today, this type of cross-section can be seen in the direct descendent of these weapons: the sport fencing blades.
So, it's not strange to find it in such a vintage swordstick. Which is very nice, by the way, I must say... :)

Thank you all for the quick reaction.
I am happy i now have vital references on the blade.
Marc's first set of pictures has precisely the same cross section of my example ... or what theres is left of it: a mere eight inches of the tip section.
I may now assume this is a leftover from one of such period dwelling swords accidented blade.
Indeed the components are nice and even have a little age patina, but i don't think they were a born set. The coupling ring shines as modern, and the handle was trimmed to fit into it. The well finished bamboo cane was hollowed for a much longer blade, plus other details.
I am glad that the blade (part of it) is genuine and so adds some seriousness to the trio.
Kind regards
Very nice swords, Mark.
