That visual explanation was fantastic.

Massive respect to the person behind this invention

A great explanation. We're always told it doesnt cut the skin because it vibrates, but ive never heard it elaborated as to WHY that would allow it to not cut the skin.

The person who invented and introduced it to the industry surely had a big entrance to the room of demonstration.

I love how uncomfortably real the animation’s are on this channel Edit: I gained 200 subscribers from this comment and I don’t even post anymore, but i am now

New fear unlocked: 'oops wrong saw'

FINALLY! A good explanation! The other time I've herd about this saw they always say "it's a special saw". Thanks! :)

As someone who has had multiple surgeries that required casts thank you for answering this question! I remember being worried about this when I was a kid.

You need to get a grip Cast-Saw: I can't

The people who invented cast saw and sawstop saw are heroes

Relatable !! Hats off to the inventors🙌

This same principle applies to a hair trimmer also 😊

The first patient testing it was a true hero

Hats off to the guy who invented it... Such creativity, I could never-

This is actually really cool. Thank you! I love your informative videos.

This gives me such a relief

True, it actually tickles

The vibration cuts/breaks the cast but massages the skin... Interesting. Must be interesting creating one of the saws.

This bro make so many good and interesting videos its fabulous 😊

Only animation that actually reliefs me

I was 9 y/o when i had my hand plastered after a fracture; and when it was time to remove it, a medical staff approached me with this saw and i bawled my eyes out. He proceeded to comfort me by running the saw against his palm to show me it doesnt make you bleed and it doesnt hurt. I stopped crying and cautiously watched how the saw went through the plaster, but only "tickled" my skin. I remember being so fascinated and wondered how it was possible. Now i have the answer!

I usually explain to my patients how it works but now I can show them this video! Thanks

Thanks for the knowledge..❤❤

Beautifully explained

As an Asian, I can confirm that in China we use chainsaws

Imagine being a blade with all ur blade friends ready to finally spin in circles but you instead start shaking

I can tell you, the moment they saw is as relieving as this animation

Wow nice, I always wondered this, thanks for the explanation!

I like the demonstrations and how clear you speak, so everybody can learn something new everyday.

The guy who did my right hand cast demonstrated this for me and explained that the blade was not rotating but just very rapidly going back and forth and touched it to his own finger as proof of how confident he was that it wouldn't cut me and that was actually really reassuring. Having a cast sawed off really isn't too big of a deal. Good video! 👍

I absolutely love your channel and the explanations you give

This channel gives me answers to questions I never knew I needed the answers to

His facts are a life saver

My bones have been very silent since this vid dropped

This was actually very informative appreciate it. ❤️

Thank you for telling us more facts 🙏

I’ve never been in a cast but knowing it’s sawed off, I wondered about this. Glad to know how it’s done now!

OMG this video has answered the question I have been asking myself for years.

This channel is my latest addiction. So rich with information.

my god, the relief of this knowledge at last is just... like scratching an itch deep down in my brain.

Whoever invented this is genius

This dude teaches me more than my science teacher

Thank god I found this😭 tysm, this was very informative and helpful! ❤❤❤

The most valuable information on KZfaq shorts today. 😊😊

His facts are never boring!!!!

These kind of creativity is why i still have faith in humanity

Had the same thought process when I was having my cast removed. Was scared that I might get injured but what I got was tickles and itch scratches that felt good to have, as well as having massive vibrations through my body

Thank you. I have always wondered this.

Lets be honest, we all want this guy as our teacher. Edit: mom I'm famous

I always thought doctors were extra careful

I love the visuals ❤

Best info channel out there fr

Nurse here. Those blades can most definitely puncture skin if the person doesn’t know what they are doing

I used to have a broken arm and not gonna lie the cast saw feels nice when it touches your skin

I was freaking the f*ck out when they pulled out this bad boy

I subscribed to you for that one👍

The cutting animation is sooo satisfying 😭😭

I love how the animation feels so real !!!

Thanks. Checked a curiosity box for me.

Wow, this is amazing content!

It doesn't cut because if the cast is applied correctly with the right amount of undercast padding,the padding protects the skin. Yes, the cast saw does oscillate, but a cast should NEVER be removed with the blade being drawn along the cast like the video shows. The cast saw can cut when dragged, especially on fragile skin such as the elderly. It does also heat up due to the friction against the cast material. Thus, it can then, in turn, cause a friction burn on the patients skin. These saws must be used with the utmost respect and with the correct supervision and training by a casting technician or an orthopaedic practitioner. Anybody that informs the patient that the cast saw CANT CUT is inexperienced in using the saw. It shouldn't cut if used correctly.

Everything is fun and games until the blade makes a 360 turn 💀

I love this channel

Thank you so much for showing this😊

"Can't get a grip" isn't a great way to say it. They grip fine, but the teeth don't move far enough to overcome the stretch of the skin

Those saws feel like heaven when they touch the skin during a cast removal

Thank you for answering a question I've been wondering about

Human engineering is absolutely astounding

bro the feeling after getting a cast removed is amazing!

I broke my left arm 5 times in the first 10 years of my life. The most painful part of getting the cast off is, weirdly enough, going back to living with a "naked" arm. You get so used to that slight weight permanently on your arm that it's strange when it first pops off and you have full control again.

I’ve actually always wondered that, thank you for explaining 😅😂

I learn more things from this channel than from school

You're a really strong person.

Doctor: "it goes to slow, let me turn on the rotate mode"

I don’t know why I didn’t look this up earlier but it has always been on my mind ever since I was 13-15 when my mom fell and had to wear a cast. I just forgot about it years later. Thank you!! lol.

Ok I’m feeling very relieved this video existe

Imagine seeing this after the Saw movie🗿🗿🗿

Precisely. The Oscillating tool works the same way. It vibrates at a rapid pace and is able to cut wood, metal, and etc. but won’t your skin. EDIT: I want to clarify myself since many people are seeing this comment. The oscillating tool will not cut your hands like a sawzall would for example. It won’t cut your hands unless you intentionally go out of your way to cut it or it comes into close contact with a part of your body where there is only bone under your skin and not much fat or muscle for the “blade” to hold on to - example: Elbow. With me saying oscillating tool won’t cut you, I am not endorsing people intentionally attempting to cut themselves, in fact, don’t do that- that’s stupid. The back and forth motion of the oscillating tool covers a very little distance. In contrast, Sawzall for example moves the blade a great distance in each direction and it has much sharper blades, so it WILL cut your skin without a shadow of doubt. Again, cutting the skin is very unlikely with the oscillating tool because the skin will follow the motion and grab onto the “blade”, like the video shows. Keep in mind- any tool can be hazardous if misproperly handled.

Probably one of your only animations that isnt actually nightmare-giving 😂

Wow! That's actually so neat. New sub!

Imagine the doctor is cutting off your cast and halfway through says “oops, wrong saw”

I want this guy to be my teacher fr fr!

Bro answering all the questions I never asked

I’ve never had a hard cast but I always thought this looked scary

Zach is the reason why I don’t have any shower thoughts anymore 💀😂

Anyways, here a brownie recipe. Ingredients: - 1 cup unsalted butter - 2 cups granulated sugar - 4 large eggs - 1 teaspoon vanilla extract - 1/2 cup all-purpose flour - 1/2 cup cocoa powder - 1/4 teaspoon salt - 1 cup chopped nuts or chocolate chips (optional) Instructions: 1. Preheat oven to 350ºF (175°C) and grease a baking pan. 2. Melt 1 cup butter, mix with 2 cups sugar. 3. Add 4 eggs and 1 tsp vanilla; mix well. 4. Sift in 1/2 cup flour, 1/2 cup cocoa, and 1/4 tsp salt; stir. 5. Optional: add 1 cup nuts or chocolate chips. 6. Pour into the pan, bake for 25-30 mins. 7. Cool completely, cut into squares, and enjoy your brownies!

This is super interesting! Just one question, though: if the saw was unintentionally run over dry skin, would it cut? Obviously dry skin is more solid and stationary than regular, moisterized skin, so it would make sense for the blades to be able to get a grip on it and slice it open.

New knowledge acquired👍🏽

"Alright, time to saw the cast off!" " Whoops, wrong saw!"

Fun fact: This logic also applies to rubber, meaning you could basically also touch balloons with these things.

Dude I’ve been wondering this for my whole life and now at 17 I finally know

Whoa I had a cast but I was totally shocked why was it so warm now I get it 😮

I swear i learn more from this guys channel than i do in school 😅

Your animations are getting really real. ❤

The nurse actually showed me how it worked and it tickles, but cuts right through the cast

This is the same with hedge trimmers! I busted my fingers, and surely thought I would have more serious injuries. There was a small, superficial cut that bled and healed after 2 days!

Zach can replace any science teacher.

Ngl the cast saw feels so good when you have had a cast on for a while

The person who made this type of a saw is a genius...

I have cp had like 25 casts and the feeling of that vibration is amazing best feeling ever when it coming off
