Fein 63502134015 2-1/2-Inch Standard E-Cut Blade
This is a 2-1/2-inch plunge cutting saw blade for the Multimaster.  This blade has smaller teeth to provide for better control and longer blade life.  The smaller tooth pattern allows the blade to hit a brad nail in flooring without destroying the blade.  Use this blade in place of a handsaw or jamb saw when there's not a lot of room to maneuver.  This blade is perfect for doorjambs, baseboards, toe kicks and flooring work.  Avoid material that may contain nails.
