They also have a tendency to shatter when they fail. If you are like me,
and tend to stick my nose close to the cut, you could get hurt.

I'm was also told, by several band saw blade gurus, that they won't last
as long as you think.

Save your money, and buy the $13 dollar ones.

Here is an exerpt of a mail message I had laying around that discusses
some of my blade experience as it relates to resawing.

The accuracy of the cut is directly proportional to the setup of your saw
and the sharpness of your blade. There are a number of factors associated with
the blade that effect the cut. These things may sound silly but they all
are pertinant when resawing (especially long cuts):

1.) sharpness of the blade (obvious, but very important)

2.) sharpness of both sides of the blade must be the same (if not, blade
will wander toward the sharp side).

3.) Are there the same number of teeth on each side of the blade? (I just
found this one last week. A 105" blade with 2 teeth per inch has 1 more
tooth on one side = wander to that side (I haven't proven this yet, I may
be bending the extra tooth back to middle although I hate to screw up a
$14 blade as an experiment)).

4.) Tension of the blade ( over tension is as bad as under tension).

5.) The blade design ( thickness, teeth per inch, tooth design ). What you
read is not necessarily the results you should expect. I am using a 1/2"
blade that is giving me a better cut than a 3/4".

6.) Feed rate (effect the life of the blade and the quality of the cut).
