Might as well link the Technology Connections video already.
Yes, it's an 18 minutes video on a 1950s toaster, you can thank me later.
It's Technology Connections.
It's always worth it. Because

Knives.
About as low tech as it gets, even for modern knives that are pretty high tech in how they're made.
But it's entirely possible for a person to make a knife with nothing but tools they can make by hand, with no need for anything other than rocks as tools. I've done it, and it isn't like I'm some kind of super genius.
You can make slightly more high tech tools if you want, and make metal knives. The caveat to that is that you have to know how to identify sources for the metal in the first place, unlike stone tools where you can figure it out by banging rocks together until you find some that make sharp edges. But making an oven that can turn out low-grade materials is realistic for a single person to do.
But a knife, in its essence is just an inclined plane done to a very fine degree. Doesn't get any more low tech than that. Mind you, there's plenty of complexity involved in all of the basic machines like inclined planes, but that's more about understanding them than using them or making them.
Knives are mankind's most important tool. They were among our first tools, and it can be argued that they were our first manufactured tools. And we still use them regularly. Some of us use them every day, multiple times a day.
That's a lasting technology in every degree of refinement.
Smelting metal (as opposed to just heating already refined metal) is a non-average skillset, though, and knapping is quite hard to master.
Honestly, kind of mind blowing even thinking of them as a technology, they're so ubiquitous. I use a knife a minimum of 10 times a day, and that's just in the kitchen, not including opening mail, packages, small medical stuff, and a ton more uses. Holy shit, where would we be without those inclined edges?
Awesome comment to read at 430 in the morning. Thank you

Bicycle
Books
Rope or really any cordage. Can't begin to tell you how handy learning 7-10ish knots has come, plus lashings
I'm curious just because I never use ropes or knots - what kind of work or activity do you do where you use that regularly?

I was always terrible with knots growing up. My father spent far too much time trying to teach me a basic trucker's hitch and sadly never got to see me really "get it". Then, when my own son was in Cub Scouts and supposed to learn some basic knots, something just clicked in my mind and I took an interest. The bowline was the gateway knot for me and learning that led me to finally apply myself to the trucker's hitch. Just such a useful pair for tying up a load. I can understand why my father really wanted me to learn it.
Now, I keep a length of paracord on my desk and will fiddle with it, practicing knots whenever I'm doing something that leaves my hands free. And ya, having a basic set of knots down is just damned handy.

INDOOR PLUMBING
I live in an apartment complex. The thought of having to share an outhouse (more than 1 if lucky) with hundreds of strangers TERRIFIES ME. And/or use chamberpots. FUCK NO
A BLESSED ETERNAL AFTERLIFE OF BLISS FOR ALL HUMANS WHO CONTRIBUTED TO INDOOR PLUMBING SCIENCE 😩

Do vinyl records count? I really like that they make beautiful noise from a simple electromechanical process.

Rice cookers. It's super low tech but works great to cook perfect rice.
I dont know about you, but our rice cooker seems quite high tech. It can even talk!

Waterwheels. Thousands of years old but still an essential part of our energy system.
Automatic (mechanical) wristwatches.
I love the idea of a truly symbiotic relationship between a thoughtfully and carefully designed mechanism and a human. I walk around and live my life, and by doing so, I give it the kinetic energy it needs to keep its mainspring wound, and in return it tells me what time it is. Always. Without fail. I just have to tweak the time if it starts to get too far off, but that’s barely even an imposition. After a good long while, it’s prudent to have them serviced, but if you’re not observing any problems, it’s generally perfectly fine, and will keep ticking along as long as you wear it regularly.
I had a cheap automatic in college, sadly lost it in a move.
But I loved it so much, kept itself wound up without issue, and it was amazing to look at all the tiny parts that made it work.
There are some good enough automatics out now at very reasonable prices.
Of course there are also crazy expensive ones also, but they all do essentially the same thing - convert your movements into time measurements 😀
Similarly, I have a cuckoo clock. I could watch the internal mechanism for hours.
