Ok, then everybody refer to knives all the time as weapons. Let's see how that works out...
Is that what I said? Or did I say that there is more nuance to that? Should we refer to alcohol at all times as an addictive drug that kills its users? We can't be this myopic. Knives are tools. Tools that can at times be used as weapons. That use is up to the end user. Rather than fighting ourselves on forums about how an axis lock mini grip is a tool but an automatic OTF is a "weapon" how about directing our efforts to educating the rest of the populace that knives can be owned for a variety of purposes and that the 99.99% of good people using them everyday should not be wrapped up into the tiny fraction that use them for unjustified violence.
We do this with cars, we do this with baseball bats, we do this with alcohol, we do this with axes, chainsaws, hammers, and thousands of other products. I own an axe to cut wood. Just because someone used it to harm someone at some time does not mean that we need to start drawing lines on how long your axe can be.
