Set of seven unique steel chisels designed for driving caulk between the planks on wooden sailing ships. All of the chisels have the same handle, not so unlike a baseball bat handle and each blade is different. Two are somewhat triangular and flat like a paddle with a third in the same shape but a longer neck. The next four are shaped more like knives. One has a pointier tip and a rounded blade. The third from the right has a sharp tip and is increasingly longer than its counterparts. The second from the right also has a pointy tip and the chisel on the end is quite a bit longer than the rest. The first, second and fourth from the right are inscribed with "JHW" and the third from the right says "solid steel".
Captain John Harry Woltman, 1894-1927, used these chisels on the schooner Mary A. Gregory to drive caulk between the wooden planks of the ship. Some of the chisels have his initials "J. H. W." inscribed on them.
These chisel tools help document Chicago's maritime history. They were used to build the wooden ship, the "Mary A. Gregory." The "Mary A. Gregory" was built on Goose Island in 1875 and was purchased by Captain John Henry Woltman in 1894. Captain Woltman sailed the ship until 1927. The ship was said to be the last of the trading schooners sailing the great lakes from the port of Chicago. She was rebuilt in 1910 by Captain Woltman at St. Joseph, Michigan. In 1927, Captain Woltman, following centuries-old naval tradition, stripped the boat and had her towed out into Lake Michigan and burned behind the Marine Hospital.
