Saw blade

A system comprising:

• a 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 and 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 of said face surface, wherein said initial rake angle is greater than or equal zero degrees;
• 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 along a length of said second portion, wherein said second rake angle 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;
• and
• a motor configured to move said blade.

A method comprising:

• providing a first blade configuration having a base and a plurality of teeth extending generally outwardly from said base, wherein at least one tooth includes a back surface and a face surface intersecting one another and forming a first cutting edge;
• and
• removing one or more sections from at least said face surface of said at least one tooth to form a second blade configuration, wherein said back surface and said face surface intersect one another and form a second cutting edge to remove material from a work piece, said face surface of said second blade configuration having a first portion and a second portion defined along a length thereof, said first portion having an initial rake angle and said second portion having at least a second rake angle, wherein said initial rake angle is 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 face surface along a length of said first portion and said second rake angle is the angle between said approximately perpendicular line and a line extending away from said base and along said face surface along a length of said second portion, said at least one tooth further including a gullet extending from said second portion of said face surface to a back surface of an adjacent one of said plurality of teeth,
• wherein said initial rake angle is greater than or equal zero degrees, and wherein said second rake angle is more positive than said initial rake angle, and
• wherein said second cutting edge is initially defined by said first portion of said face surface, and wherein said second 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.
