Koummya with nice(?) blade

[shayde78]

So I've cleaned off enough grime to see the mark. It isn't complete, as it appears a portion has worn off. To me, it looks like the leg and three tail feathers of a bird(?). In this condition, abstract enough to be open to interpretation. I'm hoping someone with a good list of known marks can match it up to something.
As always, thanks for your insights.

Oh, and a picture of the full blade again. I know folks weren't too pleased with the prior pics, so I hope these prove more useful.
