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.

What do you carry in your pockets every day?

For me, it used to just be my keys, wallet, and phone. When I started to consider concealed carry, I realized that I had a pocket knife and pepper spray that I never carried around even though it's really not much more cargo than what I already had, and I just need to build the habit. I don't have the pepper spray oriented in a way that makes it very easy to get out and use, but the pocket knife has already been quite useful; at work, cutting off zip ties or opening packages is useful. At July 4th, other people handling the fireworks were asking to borrow my knife quite a lot. The knife you bring with you is a lot handier than the knife you leave at home! Even a dull one.

I also bought an OLight Mini 2 for my keychain. Pretty nice, though I think it's only really come in handy once or twice so far. It seems to be marginally brighter than my phone light, and a lot quicker to bring to bear. It was cheap.

Things I have considered:

  • A telescoping baton. Like the pepper spray, I was considering it for dog defense, mostly, but apparently it's legally questionable to carry one and actually ever use it in a self-defense scenario. I wonder if one would be useful for anything else.
  • A lighter. I don't smoke. When lighting off fireworks for the 4th, I was using someone else's long lighter for lighting grills, and it was very unreliable, bad for what we were trying to do which was synchronize 4 different mortar tubes of fireworks at once. I thought that if I had my own lighter, I could have just used my own and not been as frustrated.
  • A multitool. These are commonly carried, but I don't know if I would use most of the functions or not. Many people swear by them, though.

I recently reported on a series of stabbings that took place in Dublin at hip hop concerts, and a recurrent sentiment I've seen expressed by multiple people independently is that a person who brings a knife with them to a gig probably fully intends to stab someone at said gig, and the fact that they were carrying a knife on their person should be judged evidence for premeditation.

I cannot fathom why anyone would carry a knife with them to a social occasion. If I was hosting a party or barbecue and someone brought a knife with them (without a good reason, like they were coming straight from work), I would mentally strike them off all future guest lists.

I cannot fathom why anyone would carry a knife with them to a social occasion.

I carry a small multi-tool on my keychain, and other than having to remember to remove it before air travel or large venue events with metal detectors, I've never stabbed someone with it in the almost two decades I've carried it. The closest I've gotten there has been on myself. Also useful as a screwdriver and small pliers. The knife on it is maybe two inches long and would be a very ineffective weapon. I know folks that carry a full-size multi-tool around, too.

Hopefully you wouldn't kick me out of your social occasions, but I suppose standards for edged "weapons" vary a lot by country: it'd be legal here for me to concealed carry a firearm many places I go, but I don't.

What day to day tasks does this help with? I have a swiss army knife somewhere but there never seemed to be anything to do with it, so I'm curious about what I could use it for.

I realize this is a common cultural difference even within the United States, but there's a lot of relevance, anywhere from opening packages to cutting zip ties to prying out heat-set inserts to breaking open containers to stripping cable to trimming plastic nubs.

My uses are a little more common than most people -- I carry the cheapest tantoized blade possible because I've had to derivit aluminum plate in the field enough that it's a parlor trick -- but still, I work in a field with soft hands.

I try not to carry to public events like a concert, but I'll admit I've had to throw mine away a couple times because I just forgot I had it on me and went to a venue that banned them.

What is "deriviting"?

I read it as removing rivets.
