Great idea, not as great as billed
I purchased one of these last fall, and the blade in Hole No. 1 was dull. Brand new product, dull blade. I thought I didn't know how to use it until someone changed my blade (to prevent a return of the product). After switch, works only ok in hole #1, and of course that means I really didn't get four functional blades. Also, be careful and don't empty the shavings over something that you can't happily access; you may need to dig through the trash when the replacement blades fall out of their storage spot - it happened to me twice.
I still use it, but don't feel bad if you buy one and it doesn't seem to work; it's probably not you!
After a long search this is the definitive sharpener
Have had several small sharpeners and all have lacked the ability to sharpen leaving a point. After a short time they break the lead and don't work very well. The Kum Automatic Long Point Pencil Sharpener leave a long point on your pencil~doesn't break off the lead and is easy to use. Easy open lid to empty the shavings~two holes both regular pencil size which is a plus. Most have a big hole and a pencil size hole. We only have use for a sharpener for a regular size pencil. I would suggest you give this a try if you want a clean cut with a long point on your pencil.
