This is solid and heavy and quality product.You will need to place a barrier between your hammer and the top of edging when hammering in to prevent damaging the edging. I used a piece of wood first and then switched to a folded towel. Use a heavy hammer like a hand held sledge hammer or heavy rubber mallet.You will want the weight of these hammer types to drive the edging in.Make sure you have no roots or rocks under the teeth of the edging. Heavy thick roots will keep the product from being driven in evenly.When starting to drive a new piece of edging in, start at the end of the new piece and work your way back to where the new piece joins the first.This keeps the the new piece from popping up higher where it joins the first piece.I need a second box,as I anticipated, but disappointed the price has jumped up $20 per box in one week since buying the first box. Keep this in mind if you need more than one box. If it is $80 or under per box, buy the additional boxes at that time.
