I have the Work Sharp and it works great, I wouldn't use it for a lawn mower blade as a bench grinder or a 4" angle grinder will work much better. I don't have to use it very often as once I got the edges shaped back up the honing steel works well, reteaching my self to only let the tip of the blade touch the cutting board has extended the life of my blades imo.
