The horse-tail grenades are shaped like goose eggs, or like drops of water, with one end pointed and the other round. The round end is not only the pouring nozzle but also the ignition point.
They're called horse-tail grenades because on the pointed end, there's an extra small pull ring. A hemp rope can be attached, making it look much like a ponytail.
At this moment, Tamas was holding the body of the grenade with his left hand, while gripping the end of the "horse-tail" with his right.
He nodded at Peter Buniel, who skillfully lit the fuse with a fire striker.
Tamas immediately stood up from the trench and swung his arm, as if using a stone sling, whirling the horse-tail grenade above his head three times until the heavy iron lump was fully powered, starting to make a whooshing sound.
Tamas let go.
The horse-tail grenade, with a hissing fuse, blended into the night as it flew towards the United Provincials' position on the high ground.
