Diana, you can use a nail-clipper to edge your decks - it works just fine as a corner rounder, I have done it on three decks! practice on some plain cardboard first though! Then you will know what distance is necessary for a successful cut. I have attached an image below with the edges trimmed with nail clippers, so you can see.
It does work well! And that is the Wildwood deck I have added another nail clipper set I did - the Robin Wood. I learned it takes three small snips at each corner to round it properly! First the main middle round, then tiny snips to take off the edges at either end of the round part
Padma, they look great!
