A Sailmakers Seam Rubber

A hard wood sailmakers seam rubber used for pressing folds into fabric.

A sailmaker is a person who makes and repairs sails for sailboats, typically working on shore in a sail loft. The sail loft consists of many other sailmakers as well. Large ocean-going sailing ships often carried sailmakers among the crew. The sailmaker maintained and repaired sails, and this required some knowledge of the sailmaker's craft and many of the tools of the sailmakers loft on shore.
