Another OXO pen I found at Staples, also on sale, was this Good Grip ballpoint. I love the black matte hard rubber design, it's a substantial pen with a short refill that has a very nice 1.0mm tip. The line didn't seem too wide, in fact I thought it was a 0.5mm or 0.7mm until I took the pen apart.
Twist the pen and two things happen: the tip descends so you can write and the pen clip disappears. The pen cannot be clipped to your pocket while the refill is engaged, so there's no chance for an oil-based ink disaster (and no need for a pocket protector, unless that's your look).
The pen is hefty, no slim Hi-Tec-C here, and easy to grip (the whole point of OXO). I like the overall design and hand-feel of this pen, if you're looking for some additions to your line-up you might want to give these a try.
