Soviet Spade Identification

Hello guys,

Just got back from Georgia and got this from from a street market selling assortments of old things.

I wasnt sure if it was authentic or not, but first time I have seen something like this. So even if it isnt I have a very heavy, and cool looking camping spade.

I suspect it is old, just not sure from when. It seems it has been "repaired" in some areas (screw at back seems to be newer and slightly different to all the other metal. At the front, bottom right rivet seems to be different to all the others.)

Not sure if the Soviet star was an add on later too.
