Query: piece of junk

Garbage. Sharpens pencils on an angle. Cheaply made. Cover comes off if you barely touch it. Feels like it is made of tin. The good reviews cannot be for this product, or they are employees/relatives/owner of the company. I will have to look for a quality, American made product like my last sharpener that lasted 50+ years. A good sharpener of this type would weigh a pound, not several ounces.
