Lebalkanique if I'm reading it correctly. Lockback navaja style knife, made in France or maybe Spain. See this older thread for more info viewtopic.php?f=30&t=56787&hilit=Navaja
. Not sure if your knife is that old or not.
Maybe some others will know more. Do a search here for "navaja" (not Navajo) to find more about that kind of knife.
