Doubtful; I feel quite the same about the Pentel Twist-Erase III, which, in a variety of lead diameters, has been my implement of choice since high school. This is not least because it excels among mechanical pencils in having the eraser be other than an afterthought - as hinted by the name, the upper barrel contains a twist mechanism which houses an eraser that's a quarter inch in diameter and over an inch in length, and which is immediately available rather than requiring partial disassembly to access. It's also, like that on the Ticonderoga, made of rubber that does its job, which you'd think would be the only criterion but go figure.
