Abstract
A loop pile cutter includes an added blade holder thumbscrew that provides an additional clamping force to hold a blade holder right side and blade holder left side against a base mounting bracket. The added blade holder thumbscrew also guides the blade holder along the base mounting bracket. In particular, the added blade holder thumbscrew inserts within a slot in the base mounting bracket. Since the added blade holder thumbscrew is removable, the slot may be closed-ended. The combination of an added blade holder thumbscrew and a closed-ended slot in the base mounting bracket reduces deflection of the blade holder from carpet tufts that resist being parted by a center row guiding edge.
