Interesting.
The scracthes on the blade a re very crude imitation of the usual yataghan inscriptions. The blade profile is very similar to the Ahmed Tekelu yataghans

The punch work on the spine is similar to what is seen on Laz bicagi / Black Sea Yataghan. Considering the population exchanges with Cretan populations and the Pontic region, this might explain the Cretan connection.
