I had to laugh when I learned of DS Arms' new Z Hawk. It's a combination of an AR-15 armorer's tool and a tomahawk.
Apparently one's supposed to carefully avoid the sharp and/or pointy bits while applying the tool to one's rifle.
Why anyone would want to add the hazard of serious self-inflicted injuries to the gunsmithing process, I have no idea!
I suppose one could argue that it's literally on the cutting edge of firearms technology . . .
