Tool review: 3-HP Tablesaws
With riving knives now required to earn approval by Underwriters Laboratories, manufacturers took the opportunity to freshen up their saws. We tested 9 of them.
Riving Knife Saws
According to the old joke, every tablesaw made in the last 50 years came with a free dust collector: the combination blade guard/splitter that sits on a shelf collecting dust. That's because most of us reason that we're smart enough not to stick our fingers into a moving blade. However, kickback can surprise even the most seasoned woodworkers, and many tablesaw injuries caused by kickback could have been thwarted by a riving knife, a steel fin located immediately behind the blade that goes up and down with it and prevents a board from contacting the teeth at the back of the blade.
Our test of today's riving-knife-equipped cabinet-style saws reveals that you'll be glad to have most of them in your shop. As we discovered, it's the subtle differences and helpful features that separate the top performers from the pack.
