The lower jaw portion has a cutter side wall, a guide side wall and an outer end wall, and the cutter side wall has an upper working surface with a generally V-shaped configuration, and a recess providing a blade seating shoulder extending parallel to the upper surface. The end shoulder at the proximal end intersects at an obtuse angle with the blade seating shoulder, and defines a reference plane. Seated on the shoulder are abutting; elongated rhimboidal lower cutter blades with end faces extending parallel to the reference plane. The outer end wall has an inner surface portion has a blade seating shoulder on its inner surface on which is seated a cross cutter blade. The guide side wall has a recess adjacent the outer end wall which provides a blade seating shoulder on which is seated a guide blade. The distal end surfaces of the guide and distal cutter blades extend parallel to the reference plane and bear firmly against the cross cutter blade which also lies in parallel plane. The upper jaw has an invention V-shape pivot portion and a jaw portion extending therefrom with a cutter side surface adjacent the cutter side surface of the lower jaw and a guide side surface. Its cutter side surface has a recess providing a blade seating shoulder on which is seated a pair of abutting elongated rhomboidal upper cutter blades.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
