How I work is why I tend to prefer paddle switch grinders. Because they're easier to feather than side switch models. I'll pay extra for a paddle switch model. I don't think I own any side switch angle grinders. Rat tail angle grinders are cool too. They have clicker switches in them which offer feather action too. In some instances always switched on angle grinders can be good too though. Come to think about it I do have one side switch angle grinder. It has a band file accessory on it. I don't use that very much. I always break the bands. I don't even know where that grinder is right now. I think I saw it in a cabinet a while back? The cabinet of tools I don't use very much.
