Avbill,
Which pen are you asking about? CSUSA sells both a "click pen" and a "clicker pen" and they are quite different.
Your original post asked about the "click pen" but it appears some people have been replying about the "clicker pen" (which some commonly call the long click to help avoid confusion).
Here is part of a screenshot taken directly from CSUSA's website:
My daily carry pen is a clicker (aka long click) from CSUSA and I love it. I like the long, one piece to show off great blanks - in my case some black walnut from my brother's property. I like the clicker mechanism - the top is broad and feels good to my thumb - it doesn't poke like some freebie trade show give-aways. I love the gun metal finish. I know some will disagree with me, but I also love the shape of the clip.
Keep in mind that I'm new here - I have only turned slimlines, cigar pens, and the clicker (aka long click), so I may very well have a new favorite next month, but for the past 2-3 months this pen has been with me all day, every day, and I really like it so far.
PS: I did have the problem that Ruby Pen Turning mentioned on one of the few I have turned so far. I fixed it the same way he did, except that I used Johnson's Original Formula Paste Wax (it's what was handy in the garage).
