An apparatus for positioning an animal carcass middle (116) and for separati ng a loin (325) and fatback portion (312) from the carcass middle (116) includi ng a dual blade loin knife assembly (260) for making appropriate cuts to separa te the loin (325) and fatback portion (312). The dual blade loin knife assembly (260) includes a z-blade (164) and a j-blade (176) in which the z-blade (164 ) separates the loin portion (325) from the belly portion (335) while leaving about a 2 inch to about a 2 5/8 inch shelf on the belly portion (355) incorporating an amount of "finger" lean while leaving a portion of finger lean (330) on loin portion (325) and the j-blade (176) separates a selected depth of fatback (312) from the loin portion (325) based on the desired profile. The j-blade (176) is positioned proximate the z-blade (164) such th at the carcass middle (116) engages the j-blade (176) subsequent to engagement of the z-blade (164). The dual blade loin knife assembly (260) increases the useable size of a shelf cut on the belly portion (335) of the carcass middle (116).
