    Having the holes in the male blades is an attempt to make the plugs lighter. . . Bwhahahahahaaaa !! The real reason is OBSOLETE. No one wanted to change ! F.E.A.R. It would be easier to manufacture them WITHOUT the holes. Less Tool & Die Maintenance for the Punch and Receiver for the thru hole ! :0) Look it up, but don’t believe the rumors.

    You can use them to directly tie wires to it

  3. havfunwithit on July 30, 2021 at 9:10 pm

    So when are you going to tell us what the holes do?

  4. 2003VZ06 on July 30, 2021 at 9:10 pm

    Just lost 3 min. For nothing 😂😂

  5. rosebudforglory on July 30, 2021 at 9:14 pm

    Well they wouldn’t “fill” the holes in — they just wouldn’t cut them out. But my bets are that it would cost millions to change the machines (think how many outlet manufacturers there would be across the world) that make the plugs to not cut the holes out and it isn’t worth the necessary design change. Many of these machines last decades and decades and decades — just replace broken parts and they run forever. You never completely replace them until a major design change requires it. Not cutting a tiny hole out which makes no difference one way or the other wouldn’t constitute the need for a change to even a small portion of the machine. Just too much involved in design and rebuild costs, equipment tear-outs, approvals, manuals and images, contract specifications, etc. etc. —just cheaper to leave it alone. Not to mention then having to explain to the world “where the darn holes went to and why”. People wouldn’t want to buy no hole ones because it’s not what they have looked at for a century and it would take a major worldwide advertising campaign to convince people a non hole plug works just the same as a holed one. Non-hole Manufacturers and the down line of distributors and stores would end up losing revenue for an unspecified amount of time, while those with the holes their sales would go up because they would pick up the sales from the companies that changed over to the new plugs. My bets are, since humans, as a whole, don’t really cotton to change, it would take a good while to get them to switch to using the new plugs. It’s the old “My great grandpa used it, my grandaddy used it, my dad used, so I use it. If it was good enough for them, it’s good enough for me, don’t plan on changing!”

    Watch this video to get no answer…smash the thumbs down 👎🏽

  7. Chris Perrien on July 30, 2021 at 9:15 pm

    Strange , I still thought sockets had locking tabs inside them for the holes. LOL

  8. Jack Patrin on July 30, 2021 at 9:21 pm

    I bought a super cheap soldering iron off Amazon once and the plug didn’t have holes in it. My perception about the quality went way down because it didn’t look right without holes.

  9. Brent Miklowitz on July 30, 2021 at 9:22 pm

    Did they put a lock out on a "back massager"?? haha

  10. Michael Renouf on July 30, 2021 at 9:22 pm

    I thought it was for lock out tag out ?

  11. J Suniga on July 30, 2021 at 9:25 pm

    Gotta love how when they suggest the feature functions as a lockout to prevent unwanted device use, the example picture of a locked device is a vibrator(wand) lol

  12. Sean Hiscock on July 30, 2021 at 9:26 pm

    Now we know the origin. But the question of why they continue to have holes can be asked. They are convenient for lockout/tagout.

  13. o t99 on July 30, 2021 at 9:28 pm

    So what no answer? So why did you bother to shoot this? Ah ah ah

  14. EIBBOR2654 on July 30, 2021 at 9:29 pm

    I have had extension and a few other cords that were made without the holes and you are right, they are noticeable when you first have one. I’ve even seen some that only had one prong or side that had a hole. That was a long tome ago and it might have been a factory mistake, a broken punch and die set, or possible a foreign made cord. I recently had one on a job that had small vertical lines pressed into the side of the prongs with that hole. Probably someone or company hoping that might help to keep them from slipping out of the receptacle on a job site.
    But the manufacturers would probably save money if they stopped putting the holes in the plug prongs. If ever you changed out a damaged plug with a replacement one on a cord, you might notice that these are machine stamped from a sheet or strip of metal. That hole is part of the punch and die set up. I read that some companies have started to replace these dies with ones that do not punch the hole making the punch and die set cheaper to make and reducing the cost by a fraction.

  15. makeintoschu on July 30, 2021 at 9:31 pm

    The title should be why American plugs have plugs. Most of the in the world have them.

  16. pippaknuckle on July 30, 2021 at 9:33 pm

    Can I buy the holes separately?

  17. Pilot Peego on July 30, 2021 at 9:33 pm

    This guy’s story has holes in it. 😂

  18. Go Ahead Make My Day on July 30, 2021 at 9:33 pm

    to make a video on the holes of a plugin find a girlfriend you’ll stop making these types of videos.

  19. dave t on July 30, 2021 at 9:34 pm

    it can be used to hold metal piece in place in the plastic injection system when it being made

  20. SuperB63AMG on July 30, 2021 at 9:34 pm

    The holes are simply a talking point.

  21. Ozzah on July 30, 2021 at 9:37 pm

    Right. So the same reason you guys are sticking with imperial units.

  22. Bill L on July 30, 2021 at 9:38 pm

    Having worked for Hubbell, Inc, I suspect the design modification is still under committee review.

  23. Gunzmith Dragonkind on July 30, 2021 at 9:39 pm

    you still never said why the holes were there.

  24. tgp nick andrew on July 30, 2021 at 9:39 pm

    If you want to extend the wire for any reason that hole is practical. If you don’t want to cut/remove that male plug you can just insert the extension wire in to that hole and wrap with electricians tape.

  25. tugquarles on July 30, 2021 at 9:42 pm

    They may have been designed with holes forever but pinching those holes costs money (time)

  26. The RebTek Channel on July 30, 2021 at 9:44 pm

    Stupid misleading video

  27. Stan Lefort on July 30, 2021 at 9:45 pm

    Basically cheaper in steel than without holes

  28. Uga Uga Uga on July 30, 2021 at 9:46 pm

    the question wasn’t answered!

  29. kalm dwn on July 30, 2021 at 9:46 pm

    The angle design is best : ASNZ, China plugs. The angle stops plug movement👍

  30. WityWot on July 30, 2021 at 9:47 pm

    I’ll put 2 cents in,
    How about a way to run it in walls and crawl spaces or any hard to reach area and placement? A wire or string or tool could be used to pull plug and cord through to its needed location.

  31. Ken Stubbings on July 30, 2021 at 9:48 pm

    It is so the user can easilly tell the difference between a power plug and the dual USB C socket

  32. Michael00172 on July 30, 2021 at 9:49 pm

    In the early 1960’s I was a trawlerman, on board electrical supply was DC, with a ground or earth pin.

    The earth pin had a hole in like American plugs, the exact use for the hole was to prevent the plug being accidentally extricated from it’s socket.

    How did it achieve it, simple, the socket switch engaged a pin directly into the earth pin on switching to power, thus preventing it from being removed whilst in the ‘On’ position facing downwards.
    That is a great idea for when there are young children around.

  33. T T on July 30, 2021 at 9:49 pm

    The answer is: no reason

  34. 林義軒 on July 30, 2021 at 9:50 pm

    I’ve bought an iron which didn’t have holes on the plug. Kind of weird at first, but it didn’t affect anything, to be honest it’s kind of cool

  35. Rabbid_Alien on July 30, 2021 at 9:51 pm

    I choose the lock out reason lol sounds like it makes the most sence. Like locking out your vibrator, you dont want someone else using that lol.

  36. Code4 Code99 on July 30, 2021 at 9:52 pm

    When I realized that there are things that I had never contemplated in to think the depths of knowledge that is behind such inoculus ideas in trivial places of reality that I and others and others commonly take for granted but I have to say after smoking this weed I’m so interested in that depth of detail of nothingness of nothingness I think I’ll take another hit at this week and sit back and watch another video of yours how fascinating is this what a wonderful day I think I’m gonna eat something 1st though I’m a little hungry but yeah I like that video and I gotta see more. Oh damn my lighter went out I can’t light my my joint..

    Can you do a video on lighters wondering about them now that I think about it

  37. MuchO's Way on July 30, 2021 at 9:53 pm

    For safety purposes. To make sure the human inserts the plug correctly & fully inserts the plug flush with outlet. The 2 holes will not make contact, thus there is no power. Actually very intelligent.

  38. Shawn Rutters on July 30, 2021 at 9:55 pm

    My extension cords use them as locks. A pin slides in so I don’t unplug them by accident.

  39. Rocky77340 on July 30, 2021 at 9:55 pm

    It’s kind of weird to hear him say, "When the holes are missing." Makes more sense to say, "When the material is missing to create the hole." lol

  40. King George on July 30, 2021 at 9:56 pm

    So there’s no answer to the question then 😦

  41. David Longtin on July 30, 2021 at 9:58 pm

    wrong it’s not to save anything because the manufacture doesn’t need to fill in the hole just take punches out of the die to not have the holes there so try again?

  42. - uɐɯllǝפ on July 30, 2021 at 9:59 pm

    I needed this like a hole in my plug

  43. Jon Loc on July 30, 2021 at 10:00 pm

    So the answer is almost as simple as "just because"

  44. Carl Beane on July 30, 2021 at 10:01 pm

    It’s to optimize turbulence to properly atomize your electric/air mixture before it enters your appliances.

  45. Kristopher FrootLoops on July 30, 2021 at 10:02 pm

    I always thought the holes helped for self cleaning. I get dirt in the female side often.
    Kind of like a Glock Rocket connector with the slots. Self cleaning.

  46. Larry B on July 30, 2021 at 10:03 pm

    "They’re not going to change a design that’s been around for 100 years"…you’re giving that as "THE reason", but you have no idea what companies are thinking.

  47. Alex Jansen on July 30, 2021 at 10:04 pm

    Stun gun chargers don’t have holes on the plug

  48. Dave Conway on July 30, 2021 at 10:04 pm

    They look like they serve as a makeshift backup breaker. Too much current and the metal snaps by the hole……sounded good but I’m talking out of my ass

  49. nolatone on July 30, 2021 at 10:04 pm

    They wouldn’t be filling the holes in, they would be skipping the step where they punch them. Which raises the question, why wouldn’t they skip a step and simplify the process? My guess is they’re using machines that have it built in.
