hello
my friend asked me to identificate this dagger
for me its a strange one due to the pointy blade and no markings.i think it may be caused by a cleaning and sharpening,the blade have many scratches along its lenghth.beside this on the edge are signs of sharpening from ricasso to the tip.near ricasso is visible a little humb that can be the remain of original blade widness.what do you think about this observation?
the grips,rivets and diamond seems to be a genuine for You?the diamond show some movement,and on the grips are visible some cracks,so meybe they once belonged to other dagger ?is it real that a maker stamp can be erased by a some clening technic?
i tryied to ID the maker of the knife but this is little hard thing i just found near identivcal ricasso and crossguard piece on this forum but also unmarked-the photo with red dot
best regards
