The shamshir with the Tulwar hilt has a continuously narrowing tip with no signs of a false edge or Yelman. the Tulwar hilt with a Tulwar blade has a noticeable though small straightish 'Yelman' spine where the blade remains wide almost right to the tip and the back edge appears to have at least a false edge which may be sharpened somewhat.
O course as we are mostly westerners (or at least ESL* speakers), we get everything muddled up describing stuff in a language not of the weapon's original makers/users.
* - ESL=English as a second language
- (As in I speak mostly American but have also learned ESL
)
