Two vintage hat makers shaping screws or wooden hat stretchers.

The slightly smaller stretcher has 1/2 inch deep heads and is 7 inches overall when closed.

The larger stretcher has 3/4 inch deep heads and is 7¹/₈ inches overall when closed.

Both have good wooden screw threads.

There is a small chip to the inside of one head on the smaller stretcher, please see images.
