Personally, I didn't care much for the click mechanism in the Woodcraft pens, but they may have improved since I worked with them. I bought 10, and don't think I made all of them, because out of 7 made, only 3 performed well enough that I felt confident in selling them. Though I'm not too crazy about the plating choices and the appearance of the clip, I have to say that the PSI "Slimline-Pro" Gel Writer is probably the most reliable clicker I've worked with. Available from PSI, Woodturningz, Pens of Color, Augum's Penworks, and numerous other PSI distributors.
