* Ketchum grenade: a 19th-century predecessor of the "potato masher" grenade made famous by both World Wars. It consisted of a wooden handle with delta-shaped wings so that Union soldiers could throw it with greater accuracy. And, consequently, with greater hope that the gunpowder-filled metal ball on top would land upside down. Causing a small metal plunger to press inward and ignite that gunpowder!
