When Brother Adrian (apparently) invades the Warehouse and threatens Artie in fourth season episode The Ones You Love, he grabs this artifact off a shelf and throws it, knowing that it will continue to come back and back and back until it injures its target or is caught. Fortunately for Artie, Pete manages to catch it. Thomas Jeffries was a notorious 19th century Tasmanian outlaw, murderer, and cannibal.
20" (51 cm) wooden boomerang, and considerably larger medium-density foam boomerang. Grain pattern on the foam boomerang screen matches the close-up of the prop as on display at the beginning of the scene.
