And, I'll bet that an independent postmortem accident analysis would
show that a very high percentage of the 8% who blamed the saw or claimed
a "complete fluke" would also find most blame owing to the operator.
Still not convinced, no. How do we know who was the sample in either?
Either may/may not be at all close to an actual overall real rate; no
way to tell from either whether one should believe it an unbiased sample
How so? Making exaggerated claims of heightened risk to drive sales
doesn't serve their purpose of increasing sales from the fear factor for
inexperienced and/or new, first-time buyers?
Pro's will judge whether the feel the feature is worth it based on their
own knowledge independent of such "statistics" but I'm sure it has an
effect on the general population of potential buyers at large...
otherwise, advertising in general wouldn't work.
And the point is????
Anybody who knows enough to know any better won't be paying any
attention to that anyway. Anybody who _is_ swayed by them is highly
unlikely to even question their validity.
And, how's anybody going to prove them wrong no matter what they say?
They can always figure out some way to manufacturer a number whether it
has any bearing on anything or not.
Who can do anything that hurts 'em whatever they say, though? They're
the only game in town w/ the product that relies on the issue as a sales
tactic (that I'm aware of anyway).
But, as was posted upthread by Scott, the NEISS database has numbers in
the realm of 30,000/annum. Dividing that out does give roughly the
numbers to justify the time clock for _any_ accident whatever regardless
of the severity. I'm surprised it's that high, but whatever...it does
seem that a 5-6X over the number of actual sampled cases would lead to a
much higher CV than 0.1 but if the sampling basis is weighted well
enough it is possible. I've no idea what sort of verifications have
been done on these and in the background pages that isn't mentioned and
I don't have the time nor inclination to go digging further.
As I've said before, imo it's just tacky, but it's SS's claim to fame so
they've got to do what they can to justify the price differential.
I was intending to add that in addition to the actual safety feature
itself (and again I have no qualms that it is _a_good_thing_ (tm) as a
general capability) many professionals may well choose SS simply as a
liability mitigation step whether they personally care or not. Sad that
business has come to that, but in today's environment a small business
has to be terribly concerned about such.
And, the biggest problem w/ the SS "statistics" is that they don't
provide any reference for their claims; they're just there in the FUD
realm of the same ilk as negative campaign ads or the "SS is going away"
nonsense of the "geezers of America PAC" scam bunch to keep the
blue-hairs in FL in line.
I saw a quote, maybe it was a signature, that said something to the
effect of very few people with 10 fingers use their blade guard, while
100% of people with 9 fingers do.
Btw, I was looking at a new DeWalt contractor's saw at Lowes a few weeks
ago. The blade guard assembly was easy to install and remove. I wonder
if it will actually get used more often.
I use staples to keep things aligned. Rough cut the sides of the
frame, and then staple the opposite sides, and make shave cuts to the
final length. I also use a fixed 90 degree miter gauge. Get decent
precision if I say so myself.
Of all the folks I know missing fingers, all but one lost them either
working cattle, farm equipment or oil patch. The only two that had much
in common were rings that got caught; one on a nail on a fence when the
fella' jumped down, another on a hay fork that got the ring...
I can think of roughly a dozen as I write either here in town or TN/VA
that I knew/worked with.
I have yet a full complement (w/ only a couple of significant scars and
neither of those were ww-related--the most severe losing a first finger
nail to the tusk of a boar hog trying to doctor screw worm in an ear
on--that hurt!) and have spent a considerable fraction of approaching 70
yr in one of the above either as fulltime or seriously involved if not
actual firstline employment.
Generally they got the piggies before the pinkies...the ill-advised
movement by the activists to force the elimination of farrowing crates
will certainly increase that if it succeeds in large volume.

I suspect it will get used more. My table saw has a Delta UniGuard on it. This is the aftermarket guard that puts a separate plastic container above the blade and a separate splitter/anit kickback fingers behind the blade. It is very easy to use. Never gets in the way. I'm guessing if all table saws came with this slightly expensive safety device, then it would get used all the time.

While I was teaching carpentry, I HAD to use a blade guard with my students.
I actually got used to it after a couple years. There is very little that
can not be easily done with it in place, once you learn how.
Well you can be suspicious but this survey was taken from a trade
magazine not normally offered to the public in general. And, my ER
plastic surgeon 23 years ago indicated that a TS accident coming in the
door was common place, pretty much daily.
"Suspicious" has nothing to do with it. It's simply a case of survey
data is only as valid as the basis under which it is taken and any
conclusions drawn from are again only valid when they are related to the
underlying population from which they're supposed to be representative
in a known fashion.
The subject survey results are the sample estimate of the population
that responded to the survey but what does that population have to do w/
any other? There's no way to know.
Hence, there's no way to use that data to make any projection on
anything but that particular sample of roughly 800 participants. It
certainly doesn't do anything to help in estimating some number of
incidents in some larger population at large.
Indeed. And basing one's opinion on a single anecdotal piece of evidence
from one single plastic surgeon seems to be unwise.
Injury data from the CPSC for the USA in 2009:
Ladder/Stool falls: 246,733
Lawnmower accidents: 86,000
All power tools: 83,204
Chain Saw: 26,593
There are 5,000 US Hospitals with emergency departments.
That averages out to 17 power tool accidents per year, per hospital.
To break it out further, in 2011, there were 694 table saw accidents reported to
CPSC NEISS, which extrapolates to the historical estimate of 32,251
cases in 2011. That averages out to 6 table saw accidents per year
Table saw is product code 841
both of these are a far cry from Leon's anecdotal quote:
"And, my ER plastic surgeon 23 years ago indicated that
a TS accident coming in the door was common place, pretty much daily."
In looking at the case file for 2009 (783 cases), the majority seem to be
finger lacerations and amputated fingertips, although there are a couple
of crushed fingers and a few kickback injuries, e.g.:
PT STATES SHE WAS WORKING W/A TABLE SAW AND A BLOCK BLEW BACK INTO HER FACE.
DX. EYE INJ R HYPHEMA CONT, SCRAPES AND ABRAS.
PT WAS USING A POWER TABLE SAW AND A PIECE OF WOOD KICKED BACK SUSTAINED
A LACERATION TO LOWER LEG
TABLE SAW JUMPED AND CRUSHED AND LAC FINGER TIP
Interestingly, the average patient was 54 years old. I suspect
the median is higher given the distribution of the ages.
