I Built a Transparent Katana

I'm thinking about improving V1 of the sword, which is obviously going to cut better because of the thinner profile, and making another video comparing that with a real katana. I was also swinging the final sword like a bat, because it lacked cutting abilities but it had a lot of power. Anyways Let me know if you’d like to see an improed version of V1, in which I fix all the mistakes I made, including a better slicing technique! Edit: I’ll do it Ps: the reason I kept the katana that thick, is because it would otherwise bend just with gravity. So the improved version of it is going to be shorter, kinda like a real sword.

"Have you ever seen an invisible sword?" Well no, it's invisible.

As a bladesmith, this pisses me off. As a bro, this is freaking awesome. Mike, if you see this, i can probably answer most of your questions about knife/sword/weapon making.

Once he showed the nokia we already knew we're in business 😂

I actually really liked the v1, the distortion makes it seem like some magical fantasy sword, i hope we get to see more of it!

The fact that the blade is so thick that it reacts like an thin hammer and not a katana. It do not cut but completely smash the objects !

You should consider making a part 2 and call it: I build a NORMAL Transparent Sword.

1:15 Nokia : 💪

Mechanical engineer here. By making a 90 degree angle between the blade and the tang in the handle you created a stress concentration there. Abrupt changes in geometry like this create localized stresses far greater than the average stress, hence why your blade snapped there. Fun video!

A true bladesmith does not make mistakes. Just smaller knives. I’d like to see a test with v1 too. I know it didn’t match the title of the video, but your blade geometry was significantly more conducive to cutting through stuff.

My engineering teacher would adore you

Your sense of humor is a nice bonus to your amazing work on the transparent katana. :)

The right angle you cut into the blade where the handle and blade meet is what caused the break, not the added thickness of the handle. The same thing happens with steel weapons - they call it a stress riser. A rounded transition from handle to blade would help avoid it.

"Glass is glass, and glass breaks." that reference made me smile :) Edit: That phrase is commonly said by a tech channel, JerryRigEverything. High quality content, highly recommend it. (Just finish this video first, it's worth it 😙)

Acabo de descubrir este canal y es increíble como llevas tus ideas a la realidad, el único detalle es que soy de habla hispana, pero con la pista de audio en español el alcance de tus videos puede aumentar un montón y alcanzar muchas más vistas, y una gran oportunidad de crecimiento para ti, suerte y mucho exito en el canal

Man this looks like a forged in fire episode seriously❤

"Have you ever seen an invisible sword?" No sir, I have not.

"When it's wet, it looks great" His expression 😭💀

another big part of why the blade snapped at the hilt isn't just about the quality of the blade, but rather your edge alignment on the hit. The katana hit the pineapple with it's edge facing upwards, which effectively moved the middle of the blade up and away from it's inertia, turning your horizontal cutting force partially into a vertical snapping force. I reckon the blade would've survived with better edge alignment, and that can be aided with better handle design to make your natural grip closer to keeping the edge straight and practice in cutting smaller targets that won't be solid enough to break the sword.

Airport security isn’t gonna like this one..
