For many years now, I have always used the black handle Xcelite Phillips
screwdrivers with the chrome shaft & black tip. I outfitted my
electronics bench with a fresh set a few years ago, and the #1 Phillips
tip is already toast. I took apart a dead stick vacuum cleaner today
that had a dozen screws down in holes, and I had to get my other #1
driver from my woodworking toolbox to finish the job. It is also
showing signs of excess wear on the tip.
The problem is that Phillips is only ONE of the standards for cross-recess
screw heads. There is also Reed and Prince, ISO, Japanese and military
cross recess. The Phillips tip will generally turn these others, but is not
a good fit, and will quickly get the gripping surfaces rounded off.
