We have a sneaking suspicion that slingshot master Joerg Sprave might be losing his mind. But we’re not going to do anything about it, because it fuels ridiculously awesome creations like this drill-powered Steaksaw featuring a cutting wheel covered in serrated kitchen knives.

And even though Joerg laments the saw’s lack of power due to the cheap battery-powered drill he used, it’s still able to easily slash its way through fresh fruit, cans of beer, and probably the occasional over-grilled steak. As dangerous weapons go, this has to rank among the slingshot master’s finest creations. And we pity the poor sap who accidentally trespasses on this guy’s property. [YouTube]
