I recently went to Staples to purchase an electric sharpener. I chose this X-Acto brand sharpener since it happened to be on sale. Luckily for me, it turned out to be an excellent product for what I needed. The X-Acto brand itself markets its different sharpeners based on how frequently they are used - the Helix Electric Sharpener is made for home or small office use. I use it about 3 times minimum per day to sharpen pencils and it never fails. The tips come out sharp and it takes about 2 seconds to sharpen a brand new never sharpened pencil. For pencils that are dull it takes around 1 second to get them to a pristine and sharp condition
The only downside to this sharpener is that you can't see how full the pencil shaving container is. If you let it fill up too much, it will overflow as soon as you take it off to empty. I recommend frequently emptying it so that you won’t end up with it being too full - then there will be pencil shavings everywhere. Other than that one problem, clean up is easy. All you have to do is dump out the shavings and replace the little catcher bucket in the sharpener.
