20+ years ago I was putting the railing on my deck and I used a couple
36" flat bar clamps to hold the railing to the posts temporarily. I
attached the clamps with the bars pointing out into the yard, not back
over the deck. I stepped back a few feet for a visual and then
walked towards to railing to adjust it. My eyes were focused on the
railing, not on the clamps, so I never saw the end of the steel bar
until it hit my safety glasses. It knocked them off and put a rather
large gash in my forehead, just above my left eye.

After I bandaged myself up and retrieved my safety glasses, I found a
deep scratch that started dead center in the left lens and extended up
to the frame. If not for the safety glasses deflecting the bar up
into my forehead, it would have gone straight into my left eye.

I still have a scar (and the railing) to remind me how important
safety glasses are.

I always wear safety glasses anytime I am working on a project or
using a power tool. I even wear safety glasses when I mow the lawn.
However I was careless at my table saw once and the damage cost about
$3000. I needed to cut out some drawer bottoms from a 1/4" piece of
plywood. Carelessly, I didn't set the blade to the proper height and
I was a little careless holding the plywood against the fence. I was
wearing safety glasses. The peice of plywood kicked back and struck
the fore finger on my right hand. It stung for a moment but the pain
went away quickly. When I looked down at my hand the fore finger was
bent where there is no knuckle but the skin was not broken. I walked
from my shop to the house (about 100 yds) and had the wife take me to
the emergency room. The bone in the finger had a clean break. It
required surgery and a plate and screws were used to repair the
break. The finger still has a lot of scar tissue but it works
normally, no tendon damage. Always take the time to set the blade at
the proper height on a table saw. If I had set the blade at the right
height the kick back would not have been as severe.

Is there a proper height rule-of-thumb for hand-held circular saws? I've
often wondered what was optimal, safe, or both.

I used to spend more time setting up a cut than actually cutting, pissed
of my foreman du-jour but I almost never had a re-do, and in twenty five
years only had one accident. I was cutting a patch for a bathroom floor
that had rotted out from around the toilet, a complicated shape that I was
cutting with a porter-cable top handle circular saw (77s were too much for
my old, arthritic hands, etc) and dur to the lack of space I was cutting
freehand, well to make an unpleasant story short my saw opened up a sloppy
ragged gash on the thick part of my right hand (where the thumb meets the
wrist) and I wrapped it in my bandanna tightly and drove to the emergency
room. I finished up the next day with 10 stitches and an ace bandage.

And yes I took the time to pack up my tools before I left.
