How to make hot knife cutter Acrylic, Plexiglass, Plastic, PVC and Foam Cutter 

I didn't want to cut the bolt, so I wrapped aluminum foil around the blade and fastened it in the solder iron, it worked too. Brilliant Idea. Tested it on various plastic and acrylic materials, worked like a charm.

Exactly what I need. Brilliant ! I'm an old hand in the workshop making gadgets. Never seen this before. Simple concise demonstration. Thanks.

What a beautiful presentation of making a simple tool to do critical job. You are a genius. Thank you for sharing it. Keep up the good work. I liked your video. Thank you.

Come one people, give this video a THUMBS UP!!! This was an EXCELLENT DIY solution!! Deserves some Thanks!

Brilliant ! A perfect example of how a resourceful mind operates, finds a way, and saves money for investment in more fun at the bench. My kind of guy, whoever you are. Bravo!

What a talent making HOW TO videos -thanks for the tip!

Just found this - I've been looking for a way to cut acrylic without having to make dozens of scores. This looks super easy and doable even for me! Thanks!!

Gave me an excellent idea... I'm going to bypass all the efforts at adapting the screw as a receptacle and use the blade holder from the tip of an Exacto knife instead. And the Exacto blade that goes with it, of course. As long as it gets hot - and it should - it should work. Thanks for the idea!!!

I just did that with my wood burner lol… I needed a hot knife and it had different size collets to put different types of tips into the end for,wood burning… so, I just slipped one of the blades from my exact ò knife into it…. Shazam! I have an instant hot knife! Works perfectly!

Great idea, thanks!

Excelente, muchas gracias 👍🏻

I think that iron made of glow plug (used in car) may be better in cutting plastic, pexi glass, pvc etc. Thanks for your innovative idea and presentation. A thumbs up!

Perfecto. Gran calidad de video. Buen gusto en acompañamiento de sonido. Siga Ud Así!

Wow! GREAT idea and execution! Thank you!

Nice bro

Very good idea that will help me make a stencil cutter with an existing soldering iron. The way you were cutting was parallel to the jaws and the bolt was rocking as you cut. Just as a tip - when to lock your bolt in a vice and start cutting with a hack saw - cut in the direction that is 90 degrees from the surfaces of the jaws of the vice thus the bolt is always supported by the jaws and it will not move as you cut.

Brilliant idea! Very good for doing details in my project! Thank you for uploading! 🙏🙏🙏

Thank you! Thank you! Thank you! :D I have a little project including cutting some plastic. I've been procrastinating for a while but today I decided to bite the bullet and do the search for a method. And what do you know, it's very close to the firsts video I've watched and I was prepared to destroy the better part of this afternoon. And your tool cuts like butter!!! Search is over :D Did I say thank you? Well, just to be sure, again thank you!!!

That was clever. Simple, but clever.

Simply brilliant. Thank you for sharing this.

Excelente idea!!!!

Very helpful nice video love the different types of demonstrations thank you

It cuts very damn neat.........Wow....!!!!!👍👍👍👍

Thanks a lot buddy! That’s a great idea!!

Excellente idée !!!!

Perfect tool to open cassette shells!

素晴らしい～秀樹感激Goodです=3

Good idea. And you can make it better by using a thin piece of copper: no need to be sharp, it's not the edge that cuts, it's the HEAT. And in the same way, use a copper or perhaps brass rod instead of the bolt. Easier to cut too. Well, is a perfect task for a Dremel saw. And to make the cutting process more uniform/even, you could increase the thermal "mass" of the soldering iron: say by wrapping the end with copper wire. That will make it take longer to heat up, but then it will STAY hot as you start to cut thicker pieces. And you could wrap the end with high temperature insulation: can get a ceramic "wool" that won't be affected by the temperature. So the idea is to heat up the end, and KEEP it hot (with the insulation and copper wire-wrap), and use the copper "hot knife" to do the cutting for you. The extra weight from the copper wire wrap won't matter in its new role of being a hot-cutter: it's not like you are trying to do delicate stuff with a light(ish) weight soldering iron.

Thanks so much for creating this video. I'm currently working on a time sensitive project. Making this hot knife cutter will be very helpful.

Very cool, and I happen to have a spare solder iron. Going to be making this for sure.

Love the music!

Simple cost effective brilliant.

Muito criativo parabéns

Tengo que agradecer esta espectacular idea, lo hice todo paso a paso y efectivamente me funcionó, corta acrilico cómo cuchillo en mantequilla; pensé que me iba a costar cortar el tornillo, pero fue fácil. Merecido ese like BLESSING

Отличное изобретение. Лайк.

You just made life more beautiful!!!

Though simple, very useful idea to cut plastic. 👌👌

Thank you for this video very helpful from a woman that needs to cut plastic shutters

Nice, innovative idea. 🔥

Muito bom, eu tava pensando em fazer só com a ponta do ferro de solda, mas isso aí fica muito mais detalhado.

nice, very useful for me

Man never thought it! Genius!

Perfect, used it and it works like a charm. Thank you for tutorial.

Excelente ideia.

Verry inspiratif good job

Great, thank You, God Bless You.

Just what I have been looking for, thank you!

I have many sheets of old acrylic laying around because up until now I couldn't find an easy way to cut it. Thank you for your video.

Jogja hadir semangat berkarya sukses selalu🍻👌👌👌👍

Cette femme à un charisme que l'on aime ou pas, mais il détourne l'attention de la pub.

Worth ful. Idea, Thanks

2024 just bought cutter tips for that solder. cheap and effortless😂 anyway this is great

No point in buying one when i have the parts to make one. Thanks for sharing.

Great idea, now to mount it as a compass to cut perfect circles...

Nice idea, could use it on foam 🚨 pvc tube burning exhausts chloride, very toxic, careful with that

Perfect video at perfect time! Thanks.

👍🏾💎 *PARABÉNS muito legal, valeu!!!*

That is just absolutely genius !

This is very helpful. But can this be use to cut acrylic in circle shape? Thanks for tutorial and in advance for the response.

can it solder as well?

Dude amazing video, respect from Turkey

thanks for this project this tool is wery useful thanks again

You are very create person. Thanks

A great tool for any shop and maker!!

thanks to you that encouraged me to try it out!! I found that it cannot cut well if it's too thick (4mm for me) if you have to cut a long line. But if plunge it straight down it will make it to the bottom. Dragging it but not through it makes the reattached at the beginning again so kinda no use LOL Nevertheless thin pieces should work like charm.

Thank you for sharing your videos Have a great time ❤❤❤

Wonder if sharpening the fine soldering tip would work in a bind 🤘🏼🤘🏼🤘🏼love it thx

Thanks for the idea.

This is what i need❤️

Woow good 👍

Nice!!

If you are too lazy, Use only solder itself. Make the tip of solder sharpest as possible with grinder. It works fine and last long. Even the sharp tip will be usefull to glue between the edges of acrylic. Btw, the idea is come from this video 🤙👍

kren idee kreatifnya dapat membantu aku boleh tiak aku coba

Muito bom obrigado
