Most saw blades don't have the strength to chew through the compressed particle board that has become so common in construction. DeWalt and Bosch's new blades, however, have extra teeth to grab the faux wood ahead of the cutting edge and literally pull the blade forward. The result: a more controllable slice that's easier on workers' arms.
As the DeWalt blade (left) works its way through cuts, eight resin-filled slots absorb the vibration that's usually transferred to the arm of the person holding it. To help the blade glide easily across rough materials, DeWalt glazes the blade's teeth with a Teflon-like coating.

The Daredevil's cutting edges (right) also have a nonstick coating to inhibit friction. Meanwhile, Bosch reinforced its 7.25-inch steel blade with manganese, an element that slightly raises the metal's melting point so that it won't warp and wobble during long cutting sessions.

We tested the blades on the same 15-amp heavy-duty circular saw. First we made 71 eight-foot cuts through a 2.5-inch-thick stack of plywood with each blade. After neither one so much as flinched, we pushed them through two layers of asphalt shingles sandwiched between two-inch-thick pressure-treated boards interlaced with 15-gauge nails.
The Bosch blade was harder to hold steady than the DeWalt, making it difficult to follow the cut line or guide it back if it wandered off. As for staying power, after chewing through three football fields' worth of plywood, the DeWalt made it through another 54 feet of shingle sandwich before getting stuck; the Bosch quit after 30 feet.

These look sharp! I am impressed! How do these cut against the Borg! The Borg hovers in your atmosphere as I speak. You should be prepared. Is the media alerted? Do they know? You need to alert your citizens, stock resources, be prepared. These saws are strong YES, but the Borg is very strong too! You humans do not know what awaits you!!
These cutting tools look really strong, amazing strong!
My dad owns his own home repair business and he lives and dies by Dewalt...He will go out of his way and pay more for a DeWalt product just simply because they never fail...he has never had any DeWalt made product ever fail....He tried switching to some cheaper supposed to be better products and he ended up sending all the saws and nail guns back within a week because they kept jamming up for simply failing.
