Boston Leather Model 5417 4ply Denver Sap:

The Boston Leather Model 5417 is a reliable impact weapon coming in at 9" long and weighing 10 1/2 ounces. With some finesse, this self-defense tool can put out significant force as the spring steel in the handle snaps to. This particular model comes with four layers of leather for a heavier, more durable experience. All Boston Leather saps are constructed of durable, heavy gauge leather that encases a molded lead weight. All Boston Leather saps are made in the USA.
