Irwin Carbon 4 Point Knife Blades combine the toughness of a traditional trapezoid blade with the increased blade tip life of a snap-off blade. Scored edges give the user 4 sharp points (vs. 2 points on a standard trapezoid blade) which doubles the life of the blade.
The 4 notches enable the blade to be extended to maintain blade length after snapping off sections of the blade.
