Claim Text:
1. A saw blade comprising: a blade body having a back edge, a cutting edge located on an opposite side of the blade relative to the back edge, the cutting edge defined by a plurality of cutting teeth, the plurality of cutting teeth further defining and a cutting direction of the blade, and a plurality of gullets each between successive cutting teeth, each tooth of the cutting teeth configured to cut a material to be cut at least when moved through the material in the cutting direction and defining a tip, a height thereof, at least one clearance surface extending from the tip in a direction opposite the cutting direction, a rake face on an opposite side of the tip relative to the at least one clearance surface and extending from the tip toward a respective one of said plurality of gullets, wherein said tips of the cutting teeth define the cutting edge, and a distance along the cutting edge between successive cutting teeth tips in the cutting direction defines a pitch thereof; and a plurality of chip limiters, each projecting from a respective trailing tooth in the cutting direction for a first distance as measured along the cutting edge in the cutting direction from the tip of the respective trailing tooth to a tip of the chip limiter, wherein each chip limiter defines the tip, a height thereof, a relief surface extending from the chip limiter tip toward the rake face of the respective trailing tooth, and a chip limiter rake face located on the opposite side of the chip limiter tip relative to the relief surface and extending from the chip limiter tip toward the respective one of said plurality of gullets, wherein: the height of the tooth tip is greater than the height of the chip limiter, the first distance is one or more of (i) within a range of about 22% to about 44% of the pitch and (ii) within the range of about 30% to about 40% of a second distance along the cutting edge, defined between the chip limiter tip and the tip of the respective preceding tooth in the cutting direction; and each chip limiter is configured to (i) upon contact of an object with the respective trailing tooth, substantially prevent more than about 50% of the object from protruding beyond the cutting edge toward the respective one of said plurality of gullets and (ii) at least partially cut the material that contacts the chip limiter tip.
