Patent ID: 8826790

Claim:
A saw blade comprising: a base; and a plurality of teeth extending generally outwardly from said base, wherein at least one of said plurality of teeth comprises: a back surface; a face surface intersecting with said back surface forming a cutting edge to remove material from a work piece, said face surface having a first portion and a second portion defined along a length thereof, wherein said first portion is disposed closer to said cutting edge than said second portion and said second portion is disposed closer to said base than said first portion; said first portion of said face surface having an initial rake angle defined by the angle between a line extending approximately perpendicular to a cutting direction of said at least one tooth and a line extending away from said base and along said first portion face surface, wherein said initial rake angle is greater than or equal zero degrees; and said second portion of said face surface having at least one second rake angle defined by the angle between said approximately perpendicular line and a line extending away from said base and along said second portion of said face surface, wherein said second rake angle of said face surface is more positive than said initial rake angle of said face surface; wherein said cutting edge is initially defined by said first portion of said face surface, and wherein said cutting edge is defined by said second portion of said face surface after said first portion of said face surface is worn away during use of said saw blade to remove material from said work piece; and a gullet extending from said second portion of said face surface to a back surface of an adjacent one of said plurality of teeth.
