I've had this pencil for over 10 years and love it. Everyone asks me about it.
The only negative is that the tip extends out quite a bit, and it can be easily bent if you drop the pencil and it lands on the tip. I've had to bend mine back into place quite a few times. After 10 years of use, I might buy a new one to replace it.
The heaviness feels great in your hand.
The price at this site is a bargain. I paid much more many years ago.
