1/ Six-point sockets.
2/ 1/4 inch drive rachet.
Last year I started using only six-point sockets and I have yet to find a
good reason to reach for a 12-point.  About the same time, I started to pull
out a 1/4 drive ratchet whenever I had to do some wrenching.  I came to this
point of enlightenment when I noticed that my 1/4 inch drive extensions were
about 5/16 inch in diameter and that a lot of the fasteners I encountered
were 6 mm and 10 mm.  So, I reasoned if its hardened steel extension is about
the same diameter as the largest fastener I usually see, then the 1/4 drive
is easily up to the task.  The smaller size of the head of a 1/4 inch ratchet
is a blessing at times.  The only thing which will make this better is when I
break down and buy one of the long length 1/4 inch drive ratchets from Proto
or Snap-On.
