Are Round up and Weed & Feed considered pesticides? To me a pesticide kills bugs. Sorry to ask basic questions. Does anyone use a blade balance? I saw one today for $150. Magnetic and bolted to a wall. I saw another that sat on a bench. $5.37. Instinctivly I would rather buy the cheap one. It was just a cone that sat on a pin attached to a base. If the blade doesn't look level, it's not. Would this work? Or am I setting myself up for trouble? Sorry about all the posts, This week has been busy!
