Ryobi 40v expand it edger. I let it grow out some just to make this edging video for you folks. 

I started edging with machinery in 1983. Cut top of the line pro for 6 years. But the Navy always looked like fun. 20 years at sea. Many a night, in a steel box, in the middle of the storm, I wished for just an hour in the grass. Now that the grass is everywhere, I wish for an hour, in the box, in the storm. Funny that?
