Blade Height
There are two competing schools of thought when it comes to properly setting the height of the blade for sawing. The first is commonly expressed thus: "Only allow the blade to rise above the work by the amount of finger you wish to lose." That is, the blade should protrude above the piece as little as possible, to prevent the loss of a finger in case of a sawing accident.
Another competing view is that the saw functions at its best when the angle of the blade teeth arc relative to the top surface of the workpiece is as extreme as possible. This facilitates chip ejection, shortens the overall distance through which the teeth act on the part, reduces power consumption and heat generation, substantially reduces the peak pushing force required, thus improving control, and causes the blade's force on the wood to act mostly downward rather than largely horizontally.

Famous quotes containing the words blade and/or height:
“During a walk or in a book or in the middle of an embrace, suddenly I awake to a stark amazement at everything. The bare fact of existence paralyzes me... To be alive is so incredible that all I can do is to lie still and merely breathe—like an infant on its back in a cot. It is impossible to be interested in anything in particular while overhead the sun shines or underneath my feet grows a single blade of grass.”
—W.N.P. Barbellion (1889–1919)
“The Woodrovian style, at the height of the Wilson hallucination, was much praised by cornfed connoisseurs.”
—H.L. (Henry Lewis)
