Small-Scale Question Sunday for July 19, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

While not exactly a bayonet, a typical multitool could easily be used to stab someone to death. And to me and most people I know the blade on a multitool is easily the most useful tool on it, by a lot. So your being ok with someone having a knife is dependant on them also having less useful tools stuck on it?

I'm specifically picturing a multitool small enough to fit on a keychain, and I have a hard time imagining how something that small could be used to kill someone. How long would the blade on something like that be, two inches?

Most "US" multitools are based around the gerber style, which usually ends up around a 2.5" 'primary' blade. You'll see Swiss Army keychain knives that closer to what you're thinking and are someone common (if considered very much a 'for kids' product, especially Scouting), but the last time I've seen one of the multi-tool-but-tiny versions was well before COVID.

They may be more common on the coasts; New Jersey and Massachusetts have much closer norms around >3 inch knives than the midwest or southwest does.

So no Leatherman? The "standard" one has a blade a bit under 3 inches.

I guess it comes down to expectations. While a Leatherman could in theory be used to kill someone, it's hardly optimised for that purpose, and my default assumption if I saw someone carrying one would be that he uses the various tools on it (including the blade) for his job. I would certainly find it surprising if I invited someone to a party and they showed up with a multitool, but that might just be a reflection of the circles in which I move (there are no electricians, plumbers or other tradies in my immediate social circle). I would probably ask him why he carried it with him, if only to satisfy my curiosity. It wouldn't be an automatic "you are no longer welcome in my home" thing.

But if someone showed up to a party I was hosting carrying a knife (just a fixed blade, rather than a multitool), my immediate assumption would be that they were a drug dealer. I think this assumption is an entirely reasonable one in Dublin.
