Massive Hewer ?

[drac2k]

I recently acquired this massive, what I believed to be a hunting hewer. The blade measures 20.5" long, 2 & 7/8" at its widest & 1/2" thick at the base of the blade. It has a sharpened edge 11" down on the backside. The heavy iron guard measures 6.5" across and the yataghan style bone handle measures 5.25" long.
It has an etched inscription on both sides, which if translated would be deeply appreciated.
