And all the rabbit holes to square cans, flat cans, integrated openings, whether key, pop top, etc, to the self heating cans for military, and survival use. Easily another video or two in there.

also on the "someone will have taught you how to use a can opener" assumption, I want you to picture three 20 year olds standing around a kitchen counter trying to figure out how to open a can of tomato paste bc somehow all three of them were never taught how to use a can opener. That is one of my most formative life experiences

[@matterlord200]

I just wanted to let you know that your videos have fundamentally changed the way I look at technology and machines around me. They've also majorly changed how I interact with many things in my life I took for granted. No one does "in depth lessons" on how a dish washer works or how to use one effectively, but your videos helped me make basic changes that turned what I thought was basically a useless hunk of junk into one of the most convenient time-savers in my house. And that's just one example! Thank you a thousand times doing what you do.

[@runsolomon]

As a little side note if you hold the can in the air while using a traditional can opener it will not destroy the teeth on it and your can opener will last forever I have found holding it on the counter rounds the teeth off

[@runsolomon]

Because the can wants to be slightly angled in the opener and the counter does not allow that

[@nomoretwitterhandles]

I found his channel a few days ago and it is the only thing keeping me sane this week lol. I am a huge tech geek myself, but my field of study is something else entirely. I just like tech as a hobby so I don't dig too deeply. But his videos have also shaped the way I view and understand certain technologies, and his dry jokes are always fun. "In depth lessons," as you put it, are something I wish we had more of today. It's what I loved about Bill Nye when I was a kid; he explained things in a way that made it easy to understand. Not everyone understands things intuitively. For example, I understand physics on a completely intuitive level, but I couldn't tell you a single formula I remember. To me, physics just makes sense. But what doesn't make sense to me are old cameras, which this TC also explained in-depth! After that video I was shocked I never knew about how old cameras even worked! It was especially ironic because I took a black and white photography class when I was in high school, but the cameras were never explained to us; we were just told to take pictures and process them and never go into the red room when the door is closed. To think I missed out on so much knowledge because I had a lazy teacher... yeesh! I'm glad this guy popped up in my recommended feed one day. His channel is the brain food I've been craving after rotting away on the internet for so long. It's like the more you learn, the more you feel in touch with the world around you, and the easier it is to step away from this oversaturated false paradise. You were kind for commenting, and correct for thanking him. TC is changing lives, no doubt!

This fits oddly well with the side discussion: “I’ve come up with a set of rules that describe our reactions to technologies,” writes Douglas Adams in The Salmon of Doubt. 1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works. 2. Anything that’s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it. 3. Anything invented after you’re thirty-five is against the natural order of things."

[@allenjunge4127]

9:35 having worked in a grocery store, i can say with absolute certainty that the taper is there for better stacking. The ravioli cans will slide off the rim of another can easily, while the taper makes it impossible without also knocking down the can beneath it. Those cans are a blessing when stocking shelves

[@AndrooUK]

I'm pretty sure British ones have regular shaped tops with the ringpull, and tapered bottoms. You can still use a tin opener on the top ringpull side. (Well, except Heinz that just refuses to make stackable tins.)

But there are some cans that don’t stack well on top of others. I’ve had cans from differing brands that would stack together, but the can would stack fine on other cans of the same brand. I hate canned food in general. I usually opt for fresh; however, I do like a can of green beans occasionally

But it also made recycling a lot easier, we would remove the labels from cans take the top and bottom off, wash all of it and then smush the now unsupported tube flat, which saved a great amount of space in our recycling bin having just a bunch of flat cans and flat lids

It's funny! I had seen the safety opener a long while back used by somebody. I thought it was a very good product and looked for it and instead got the 2nd type of opener you mentioned which didn't work well at all.

Hi @ElectoBOOM, didn't expect to see you here! Apparently people with similar interests watch similar videos. Did you, like I did for a moment, think an electric can opener would be possible? Touching the can against two electrodes, with a frequency high enough to only penetrate and heat up the upper layer, and high enough current to melt it? Seems safe enough for me. Since I'm a father of two without a yt channel, I would love to see a video of somebody (that is not me) experimenting on that!

You may be disappointed by it. I like the side cutter style, but I have also found enough cans that it won't work on because they have different shape seams that I have reverted to the regular style because it always works.

Not sure if Walmart is in Canada mister Mehdi, but a quick online search revealed several options regarding safety can openers.

[@Linkintime1]

When I was a teenager, the lawnmower my parents owned had a self propelling feature which didn't work. This made the lawnmower a heavy push mower. The need for a replacement wasn't very high for my parents despite my complaints. This one worked just fine. When I moved out, however, they promptly bought a riding mover.

[@Huntracony]

[@SerunaXI]

9:00 When I got a "safety" can opener for the restaurant I work at, my main reason for doing so was that the cooks could get a spatula in the cans to get more product out of the cans without the burrs left by traditional can openers slicing up the spatulas. A can opened with a safety opener is far less likely to damage a rubber spatula and cause physical contamination concerns.

[@GarNelson1]

I never considered using my side-cutting can opener on pull-tab soup cans. What an obvious, but totally overlooked solution to stuff staying in the can when it's supposed to be in the bowl. I will be trying that with my next can of soup or tuna fish. Thank you.

I learned the hard way that tuna fish cans are a problem with side cutting openers. You cant leave the lid on then invert the can and squeeze the top in to get all the liquid out. I pull out the old top cutter only for tuna.

This brings back memories. Back in 1996, I worked for a short time with the person who invented this design. (or so they said as there was no Google back then). One of my first jobs was transferring the hand drawn design into Autocad. At the time this Can Opener was a huge headache for this very small company. They were trying to release a redesign of the Can Opener, but Starfrit had copied it illegally. The Starfrit copy was a bad reverse engineered version that didn't work properly, giving this style a bad image. On top of that, the owner went to a lawyer for legal advice on sueing Starfrit on the patent infringement. The lawyer said that Starfrit legal department was so big, his company was sure to go bankrupt before they could win. I left the company after a month but the owner was a brilliant engineer. I did notice about a year later, the design I copied into Autocad for them being sold in a store and so I bought two on the spot.

I like to imagine sometimes that I'm an archeologist four thousand years in the future. I have a can opener in front of me, and I have no idea what it's for. Thankfully, the internet still exists in some form, and after some electronic archeology, I come across a few videos. Maybe some of them explain what a can opener is used for, broadly speaking. But maybe they're not too detailed about it, and I still have questions. And then I find this video. It goes into such fine, unnecessary detail. It's a goldmine. A godsend. It not only explains, and describes, but visually demonstrates. It goes into the why, as well as the how. It's every bit of information I could wish for on just what a can opener is, as a far future archeologist. And, as this archeologist, I could just kiss the author, because they so distinctly call out that one pitfall of history. "It's a fact of life. Everyone knows how to use one of these." Maybe everyone did four thousand years ago, but not anymore. When a given piece of society becomes so ubiquitous that nobody bothers to explain it anymore, it leaves historians tearing their hair out, so I appreciate the effort to preserve information even about things so mundane as a manual can opener.

When I found out people actually default to buying to old type of can opener, I was genuinely surprised.

[@caseysmith544]

Did your can opener say Pampered Chef on it? Those are a Garbage piece of metal; they look like a standard but have the parts on each lever the top part on one and the bottom part on another and have to be set up right before use or they suck thus making an old design less effective. My mom still has hers but uses a standard as this particular version has a hard time with cutting the tops on some generic cans from a Statewide Chain of Grocery stores in South Dakota. There are several reasons why we stopped using the stupid piece of crap.

I bought one of these newer openers from a famous Chinese shopping channel. I never knew they had been available for so long. To me, it was something new. It came with no instructions, but eventually, I worked it out for myself. On first use I thought it hadn't worked. The tin still looked the same. Curiosity made me try to lift the lid, and voila, the lid came off. Clean, not sharp, and yes, the tin contents slid out effortlessly into a bowl. Great. But it was quite an effort to operate. I wished the wings for turning were longer, perhaps offering more leverage. My Mum, who has arthritis in her hands is unable to use it easily. I decided to persevere with it, and actually, either I have got more used to its operation, or it has, like a new car, run in. I love it now. Also, the safety angle of it strikes me as being great not only in the home but when out camping or caravanning, with no sharp edges of freshly cut lids. Better for the user, and those who deal with the discarded cans in the rubbish.This video connected with me on every level. You took the lid off the subject perfectly.

My father opens cans using the "traditional" double-cog opener, however does it backwards: the cut is along the outside (cutting through the label rather than the lid / holding the rotating handle facing up instead of sideways). This solves a couple of problems, the whole thing comes off so it's easy to get food out, and the lid can't fall in. However, it takes a bit more effort to cut, and still leaves sharp edges. It's a good compromise however!

Velcro shoes, for instance. How are voice assistants advertised, for example? Probably not as a way to make computers easier to use but rather as a mere convenience.

Because of this video, now I also have one of the superior can openers! My favorite part about it is that it's more hygienic - the regular can openers use a blade that is dragged not only through the lid, but also through the can contents themselves and they leave the risk of the lid drowning in the can contents which is also sub-optimal. Because of how this double seam cutting can opener works, its blade doesn't make contact with food at all - the only things it does contact with during normal operation are metal, lacquer and compound. Sometimes I can even see how the compound stretches and rips when I lift the lid off a can, further proofing that nothing that may have been left on the can opener's cutting wheel has a chance to make contact with food

[@_Michiel_]

Hi! Great video! Thank you for posting it. I do quality control in a factory where we put vegetables in cans. Beans, lentils, red cabbage and such. For certain quality control points we have to open the cans using these safety openers. They have two drawbacks in my opinion. 1st : they don't last that long. Admittedly we use them more often than most households. About 18 cans a day per production line. Times three to five production lines; you can do the math. After a few weeks we need new ones because they will not cut deep enough anymore to open the cans. So we buy them by the dozens. We use the 'normal' ones as well (for other control purposes) and these last endlessly. We have a few spare ones just in case one breaks down, but otherwise we never have any problems with them. 2nd (related to no. 1): we use cans of different sizes. Now larger cans (for instance 800 ml - sorry, we use metric 😁) are made of thicker material than the smaller sizes - say 125 ml. Now when we use the safety can openers on the large cans, we can't use them anymore on the smaller ones due to the difference in total thickness of the seam. So we have to have an opener dedicated to the small cans and another one for the larger cans. The 'normal' can openers do not have this problem at all. Other than that I completely concur with your findings : safer, no rim to restrain the goodies in the can from coming out easily, clean, et cetera. Love your videos. Please keep them coming!

[@galaxyanimal]

Definitely. My family had one of the safety openers as a replacement for a busted standard one, but it ended up breaking far sooner than the normal one. The problem isn't the cutting edge going dull, it's the wheel no longer clamping onto the seam. Also, you could probably use the can openers from the small cans to open the big ones after they stop being able to open the small ones if it's the clamps going bad.

[@Graham_Langley]

You'd have thought that the wear issue would have been sorted by now - the original Metal Box Company one that came out here in the UK in 1969 had exactly the same problem.

@@pshalleck I think it was just a couple years, compared to close to 10 for the conventional opener. It might have just been a cheap can opener.

However, I do come from a big family, so we almost always had at least 2 cans of anything.

[@Spo8]

The big thing that jumps out to me here is that one of my main reasons for using a can opener is when opening a can of tuna, which for me always involves taking the now-detached lid and using it to squeeze/strain out the water the tuna was packed in. In that case, having the lid fit inside the can is actually really useful.

Also on your comment on wearing out. I've had so many of the standard cutting type lose their sharpness and start to do a bad cutting job.

there's even a step in between the safety razor and the straight razor: the injector razor. safety razor style handle design gives it the same maneuverability of a safety and hard-limits the severity of any accidents, but the replaceable blade is thick and inherently rigid like a straight razor. the blade loading process is somewhat more involved and forceful, however, requiring a specialized loading cartridge.

I thought it might be only work for people who do facial shaving, but no, it's been easier *everywhere*. Gimmicks like swiveling heads and 5 blades couldn't approach it. Changing the blade isn't scary at all; it's a butterfly closure so you barely need to touch the blade at all. Water doesn't collect so it doesn't rust or mold.
