Way beyond a Phillips and Flathead.

I found this post from Instructables (via Make) about all the different types of screws. I had NO IDEA there were this many different types. The Phillips II and the Pozidriv are probably my favorite. But then again, there are so many.
“Pozidriv is similar in appearance to the classic Phillips crosshead, but in fact is substantially different. On close examination you will notice a second set of cross-blades at the root of the large cross-blades. These added blades are for identification and match the additional makings on the head of Pozidriv screws, known as “tick” marks, single lines at 45 degrees to the cross recess. So, the marks are for identification purpose. Pozidriv also does not have the rounded corners that the Phillips screw drive has. The tip or the driver is blunt which also helps it to seat better into the recess in the screw, unlike the Phillips which comes to a sharper point.”
