What do you get when you introduce the Slingshot Channel guy to a traditional African assegai spear? Pretty much a transformation from a steel spearhead and stick to a "rubber powered and 'chambered'" spear-throwing crossbow.
First, Joerg Sprave shows how the spear is traditionally used -- stabbing and throwing. He humbly admits he's not very good at throwing it and moves on to what he is good at: transforming an already deadly weapon into something even more intimidating.
First, to cock the giant crossbow weapon custom built by Sprave. Put the bungee cord around the tree to help stabilize the weapon. Straddle the contraption walking backward as the heavy-duty rubber bands -- 200-pound draw weight -- are pulled into place.
Now, load the assegai muzzle-style into the weapon. Point the weapon toward the target and shoot. As you might expect, Sprave's shot using his giant crossbow slingshot was far better than his manual spear throwing.
His straw-filled arrow target not being test enough of his machine's ability, Sprave tries it out on a wooden trunk. How did it go? Well, let's just say Sprave had to put the trunk on the ground and use his body weight to keep it steady as he struggled to remove the steel spearhead.
Watch the episode for yourself:
The assegai, according to Sprave, was developed by Shaka of Zulu, an African tribe. Much to his pleasure, he points out that the Zulu's call it "the beautiful stabbing."
