I fully agree. No Cyrillic here!!!
It is just a not very literate attempt to imitate foreign letters.
They also imitated Polish, German and Hungarian inscriptions with rather comic results, forged Solingen and Hungarian markings with very local flavor etc.
On the other hand, Europeans exported gazillions of sword blades inscribed "Fringia", a place that, to my knowledge, never existed ( correct me, please!). This was a corruption of Feringhi ( foreighner, European) just to convince the "locals" that they were buying a real import stuff! Come to think of it, not much difference between the two approaches
