The Pocket Screw Driver (the thick looking black "pen" on the left side, when looking at Chuck's pocket protector) is a General Tools 4-in-1 Pocket Screwdriver available at The Home Depot for just under $2.00 plus tax. I Discovered what these were several months ago but this particular thread seemed dead and when I posted that I knew what they were, no one responded. Chuck only actually uses this screw driver on one episode in season one (when he makes adjustments to a video game hand gun a young customer is using). When you see the close up shot of Chuck making the adjustment there is no writing / logo of any kind on the screw driver. The prop dept. either covered over it with paint or tape or they chemically removed the logo, likely so they wouldn't have to pay General Tools a product placement fee.
As far as the blue and black pens go, Pinder91 is correct, they are the FORAY brand and are only available at Office Depot. The pens with the word FORAY inscribed on the pocket clip have been discontinued, they pocket clip now only has the Foray logo on it.
Additionally, 0.5 and 0.7 mm tipped pens were used on Chuck, with the 0.5 being used for at least the first episode while 0.7 were used throughout the rest of the series. I know, it's a nit picky, geek, er, I mean nerd thing but hey, screen accurate is screen accurate, right?
For those looking for the correct Foray pens, I might know a guy.
With regard to getting BUY MORE printed on your pocket protector, I simply found a good image online and then made color copies (adjusting the print size until it fit on the pocket protetor). I used Avery brand name tag printer paper.
