I've started using this pencil sharpener over a year ago. It lives in my pocket, which seems to be a harsh environment. The plastic hinge gave out over 6 months ago and was replaced with gaffer's tape. I replaced the blades a couple of months after that. The top lid is now almost cracked all the way through and it's time for a new one.

This is a Palomino - KUM Long Point Metal Pencil Sharpener available at Pencil World Creativity Store. It's the best pencil sharpener I've ever owned. I use the Forest Choice pencils also available at the Pencil World Creativity Store. Great pencils

It first sharpens the wood and then you insert it into the second hole to sharpen the lead. You can get replacement blades.

While the outer case is falling apart the sharpening part is just fine so I broke the case off of it. I can use it as a backup when I can't find the new sharpener.
