Magna-Matic staff...I have some questions about your product. Let me start out by saying that I suck at sharpening blades. I just don't do a good job. My main question is: is it easy enough for someone with no experience to sharpen blades using your product? I have been having my local lawn mower shop do it for me, but that gets rather spendy. I'd rather spend some money on a high quality product than hand it to them for something like this. Also, I have all different types of blades...high lift, low lift, mulching, gator, Exmark Navigator, etc. Will your machine handle all of these? If you could I would like some info on which unit would be best for me and possibly some quotes. Any information would be greatly appreciated. Thank you for your time.
