2-3/8” x 1-1/4” x 1/4” Corrugated Back Rosette Straight Knives for 4-3/4” Holder (AC821)

The CB191 is a set of corrugated back straight knives — 2-3/8 inches wide, 1-1/4 inches tall, 1/4 inch thick — for use in the 4-3/4-inch Schmidt rosette tool holder (AC821). The larger 2-3/8-inch knife width corresponds to the cutting radius of the larger 4-3/4-inch holder diameter. Straight knives produce the flat base profile cut on the rosette block before profiled rosette knives cut the decorative pattern. The 4-3/4-inch holder produces the largest rosette block in the Schmidt system, appropriate for large-scale architectural door and window casing assemblies. Corrugated back locking mechanically secures the knife in the holder. For the 4-3/4-inch holder body, see AC821. For straight knives for the 3-1/2-inch holder, see CB190.
