More Information
Summary:An apparatus for trimming venetian blind slats is provided wherein a hand-held housing carries a removable anvil and blade; the blade is adapted to slide across the anvil, thereby causing a shearing action. The cutting surface of either the anvil or the blade is crowned so that the shearing action begins between the edges of the slat and extends transversely to each edge of the slat. A guide is provided to constrain the blade to a repeatable path across the anvil. The blade is driven by a lever actuated handle which extends longitudinally in a direction parallel to the longitudinal axis of the venetian blind slat. Operation of the handle by the user extends through a linkage connected to the blade to drive the blade across the anvil in a guillotine fashion. The removable blade and anvil can be made of hardened steel. A jig is also provided to facilitate trimming a predetermined amount of material from a plurality of slats.
