The tow worm is used for cleaning your musket in the 18th Century. The worm is threaded so you can attach the worm to the end of your ramrod. You can also use the worm to retrieve a lost patch in the bottom of the barrel. The worm is made of steel and threaded with 8/32 male threads. The worm measures 3 1/4″ tall and about 3/8″ round. This will work well for a 40 caliber and up to 58 caliber.
