These came along with a Bridge City Tool Works collection, but are unmarked. The blades can be positioned at the end like normal or near the center like a double square. Graduated set of six. Sizes: 1 3/4, 2, 3 3/4, 4 1/2, 5 1/2, 7 inch. The 2 scribes are among the best we have seen. They have additional points stored in the handles.
