Each baseplate has a planer section and a flange, with the baseplates joined together and the flanges generally curving away from each other and forming a longitudinal slot therebetween. A replaceable pack assembly includes a pack of parallel planer leaves separated by spacers. The replaceable pack is removably attached to the baseplate assembly with engagement edges of the leaves of the replaceable pack engaging the longitudinal slot.
