O.K. Yelman'-it is, probably same word like in russian Єлмань.
That is when the the blade is larger and heavier at the end -to add greater power to the cut. Is it same for simple sabre (as in your post #4 picture #3) that have other side sharpened, but without changing shape of the blade? (Good for cutting both ways, and for thrusting)
Thank you for extending my vocabulary
