I received this Presto Eversharp Electric Knife Sharpener as a gift about 5 years ago and it still works great. I was hesitant to use it at first, as I was new to the "kitchen scene", but after following the directions and trying it out a few times to get a feel for it, it was really easy to use. I invested some money in a set of nice knives and I knew I needed to sharpen them for effectiveness as well as for safety. So now that I am a master chef (in my family, anyway) I always keep my prep knives sharp and it makes a huge difference in making cooking fun if your knife actually works! It is so much safer to have a sharp knife so I don't have to struggle with a dull one and risk cutting myself. With this machine, just go nice and easy and don't force your knife downward - let it do all the work!
