Putting lols and political baloney aside, this badge is kind of correct, but possibly not in the way it's maker intended.
Let's get esoteric.
Knives and axes have a shared origin, handaxes (not hatchets) being specialization of early heavy duty knives.
At conception, around two million years ago, they were tools of work, survival, and life improvement, not weapons.
Their ability to be used by us to kill animals for food and sadly to kill each other was a later discovery.
Awls, and later adzes are also some of the earliest tools. In fact to my knowledge, the adze has remained peaceful throughout its history, never being developed into a specialized weapon.
Early spears are harder to pin down, as wood doesn't preserve well in dirt, but in its most basic form it's just a sharp stick. It's very likely that they were developed as early as the "mode 1" tools. Mode 1 being what archeology boffins call the simplest axes and knives.
While the earliest use of a spear may be difficult to totally know, given that modern chimpanzees make and use spears for hunting, it's likely that our prehistoric ancestors used them for the same purpose. So, not necessarily invented for killing other humans, still a violent origin.
The same goes for the much later development of the bow and arrow. Probably made for hunting before war, but its use for both would have been immediately apparent to the first users of them.
Swords, invented probably a million and a half or more years after knives were really just a knife specialized for killing other humans. They're not that helpful for hunting, and have very few uses outside of putting a sharp object into an objecting opponent.
Guns share the same sad origin story as swords. While they are clearly the best hunting tool available today, and once they became cheap enough for a common person to afford they drastically increased the survival chances of pioneer types, they were created as weapons of war, and for much of their early history that's all they were. War being the worst human invention so far.
Tl;dr
Many human inventions (especially ones that appear on the history channel) have been inspired by violence at best, and at worst violence against each other.
Knives however are inherently, from the beginning of our history, a tool first and a weapon second.
