Dear Jim, 
 AFAIK, the locals put  either a single mark on their blade, or the entire panoply: eg,  Gorda + something else, Gorda and "little bees" ( stars, essentially), TK and  Vivat Hussar or Virgo Maria, Patrona Hungariae ( misspelled, as a rule). It was a marketing tool, not different from any other culture. 
 
 
 Dear Spiral, 
 Never seen or heard of a fish on Caucasian blades. Old Mamluk swords apparently often had a fish as a handle fitting, but that's too far away and long gone:-)
