It is confusing

Several places advertised screwdriver set which had one crosspoint and two 
or more phillips screwdrivers in the same set. The Pollicis SETS sold by 
Micro-Tools come in a 4pc set marked phillips or a different 4pc set marked 
JIS Type S. Their JIS set should be a good bet.

I think Walt posted a link a year or two ago which had pictures many of the 
different styles of screwdriver tips (but not JIS crosspoint). I think it 
was

About the only description I found is at (search for JIS, it is halfway 
down)
http://www.answers.com/topic/screw

It seems the key difference between phillips and JIS is that the phillips 
head was designed to cam out the driver (for electric drivers). Yet many 
phillips screwdrivers are advertised as resisting cam out.

You're surely right about the naming being inconsistant. How about "Ames' 
Professional JIS Phillips Green Handle Screwdrivers"

Of course many phillips drivers are also called Xpt.

The dearth of crosspoint drivers could be due to catalogs incorrectly
labeling them 'philips'. e.g. this LeeValley set.

While labeled 'Philips' it is clearly a crosspoint set. The clue is that
the tips are listed as #1, #0, and #00. A true #1 philips tip is way too
big to be practical in this set. My lousy scan shows a #0 philips point
(silver) and a #1 xpt (black) for comparison.

Another clue that they are incorrectly listed is that the xpt shown in
the scan was from another LeeValley set I purchased a couple of years
ago also labled 'philips'. (and a nice set it is too by the way,
recommended, however the slotted tips aren't of much use)
